Foreword

The Tomato Genetics Cooperative, initiated in 1951, is a group of researchers who share and interest in tomato genetics, and who have organized informally for the purpose of exchanging information, germplasm, and genetic stocks. The Report of the Tomato Genetics Cooperative is published annually and contains reports of work in progress by members, announcements and updates on linkage maps and materials available. The research reports include work on diverse topics such as new traits or mutants isolated, new cultivars or germplasm developed, interspecific transfer of traits, studies of gene function or control or tissue culture. Relevant work on the Solanaceous species is encouraged as well. Paid memberships currently stand at approximately 94 (includes those paid in 2009 and beyond) from 16 countries. Cover: Design by Dolly Cummings. Bacterial wilt incited by Ralstonia solanacearum is a serious threat to tomato production in many humid tropical production regions. Breeding for resistance has been a challenge due to multiple strains of the bacterium, variable environmental effects on disease expression, largely unknown genetics for resistance, and linkage of resistance to small fruit size. Locating molecular markers tightly linked to resistance genes should be a boon to future breeding efforts and with the tomato genome now sequenced this research may advance much more rapidly than in the past. This years‟ feature article explores the major sources (“roots”) of bacterial wilt resistance and thereby sheds light on the relationships of genotypes that could be used in studies to locate molecular markers. Precision in the exact identification of sources is hampered by a lack of information or by conflicting information. Unfortunately some of the old sources are no longer available. If you read the article and have information that would help us improve the article please contact us. We live in an electronic age and if we get better information we will put it in the article and future versions may be better than the one published in December of 2010. If you have seed of a rare source line send it to us and we will see that it gets in a gene bank. Thanks for your help.

Announcements From the editor:

Help I‟ve fallen behind and I can‟t catch up! The 2010 TGC is late as a result but it is still 2010 so it could be worse- my apologies for the delay. This is our first year of our “electronic only” (see below) format and we are determining how to proceed. No dues were requested from the members in 2010 as most (but not all) costs are associated with printing and mailing the report. On the web we will post only the Table of Contents for a year and will mail a link to an electronic version of Volume 60 to members who paid in 2009. We can also send a printed version to those who want one and will pay to have one sent. Members will receive an email about this option. The cost would be $20US for domestic members and $25US for foreign members. Make checks payable to The University of Florida from a US bank or a bank with a US affiliation. Sorry no credit cards can be used. If you do not have easy access to a bank with a US affiliation we can accept cash in US dollars. For those who only want the electronic version we will ask for dues of $10 per year starting in 2011. Members will receive an email about this in spring 2011 but send in your dues at any time, either for electronic only or for electronic and printed versions as per the prices stated above.

I have not been happy with the key word search of the TGC Reports available on our website: (http://tgc.ifas.ufl.edu/) as it picks up words in areas outside of the reports such as from the Table of Contents and thus is somewhat messy. We have discussed a way to fix this and hope to have it fixed in 2011.

You can see that there are only 3 research reports in this volume. This epitomizes the trend we have been seeing over the last several years as researchers are not sending in reports. Perhaps this year‟s dearth of reports is due in part to the change to an electronic only format. However, I do see a place for the TGC here in the 21st century and plan to keep moving forward. I hope you will help by retaining your membership or becoming a member if you are not presently one and by sending in reports, varietal pedigrees etc.

Last but certainly not least, my heartfelt thanks to Dolly Cummings who keeps TGC business in order around here. Thanks to Dolly and Christine Cooley who work on the website updates.

Summary Several national tomato breeding projects began work on developing varieties

resistant to bacterial wilt over 60 years ago and several varieties created in the 1950s, 1960s, 1970s and later on are still found as reference varieties in many recent publications dealing with the genetics of resistance. From the beginning there were many exchanges of resistant material between the breeding programs that are difficult to retrace because published information is scarce. As a consequence the source(s) of resistance of the reference varieties, and the relationships between these varieties are often unclear. This paper provides a synthesis of the relationships between the breeding carried out in Puerto Rico, the USA (North Carolina, Hawaii, Florida), Japan, the Philippines, the French West Indies, and Taiwan, the main sources of resistance that they used, as well as the parentage between the lines they created. The limits of the reliability of our results are explained. The information on the resistance of many bacterial wilt resistant lines to other vascular diseases is also summarized together with some other peculiarities, in order to provide a synthesis useful for breeding bacterial wilt resistant tomatoes and for further genetic studies of the resistance patterns.

Introduction Bacterial wilt is caused by the pathogen formerly known as Pseudomonas

solanacearum, transitorily renamed Burkholderia solanacearum (Yabuuchi et al., 1992) and presently accepted as Ralstonia solanacearum (Yabuuchi et al., 1995; Vaneechoutte et al., 2004). Developing varieties with resistance has challenged tomato breeders for over 60 years for several reasons. Strong interactions are observed between resistance, environmental conditions and strains (e.g. Kelman, 1953; Acosta, 1963; Krausz & Thurston, 1975; Messiaen, 1989; Peter et al., 1993; Prior et al., 1994; Hanson et al., 1996; Jaunet & Wang, 1999; Balatero et al., 2005; Hai et al., 2008). Further, several defaults are often associated to bacterial wilt resistance, such as small fruit size (Acosta et al., 1964; Gilbert & Tanaka, 1965; Scott et al., 2005), bitterness due to high tomatine content (Borchers & Nevin, 1954; Mohanakumaran et al., 1967; Digat & Derieux, 1968; Messiaen, et al., 1978), green gel around the seeds and epidermis cracking (Acosta, 1963; Cordeil & Digat, 1967; Daly, 1976). The difficulty in developing resistance with adaptation to heat and with good horticultural features, in particular fruit firmness and large size, has been reported by many authors (e.g. Kaan et al., 1969;

7

Opena et al., 1989; Celine et al., 2003; Scott, 1997; Scott et al., 2003). It is also very difficult to combine bacterial wilt resistance to resistance to root knot nematode (Messiaen et al., 1978; Prior et al., 1994; Deberdt et al., 1999 a & b).

Kelman (1953) and Acosta (1963) reported the first surveys of the early screening trials carried out during the first half of the 20th century, in the USA and other countries, with hundreds of tomato varieties. The very limited success obtained at that time outlined the difficulty to identify highly resistant material. The breeding for resistance took on new momentum after World War II. Sources of high levels of resistance were identified and used for breeding. The material most widely used nowadays as; controls, key source(s) of resistance for ongoing breeding programs and/or for genetic studies was created in the span of time running from the 1950s and 1970s. Our main objective was to draw a worldwide historical outline of the major breeding inputs of this period, in order to get a global picture of the key original resistance sources used, of the major breeding lines obtained, and of their relationships. Indeed, as information on these topics is scarce, scattered and confusing, it is useful to sum it up for the sake of present and future research on tomato resistance to bacterial wilt. The major programs were carried out (1) in Puerto Rico, (2) in US Universities (North Carolina, Hawaii, Florida), (3) in the Horticulture Research Station1, Japan, (4) in the University of Philippines College of Agriculture, (5) in the French public institutes INRA2 in Guadeloupe and IRAT3 in Guadeloupe and Martinique (French West Indies), and later on (6) in AVRDC4, Taiwan.

1. Primary historical breeding programs, their sources of resistance and germplasm flow between programs

The main accessions used and created in the major research and breeding programs of the USA, Japan, Philippines, French West Indies and Taiwan, as well as their relationships, are outlined in Fig. 1. For the sake of clarity the accessions listed are limited to the major ones, i.e. those which are most frequently mentioned in the literature for their high level of resistance in worldwide trials, or for which the sources of resistance have been published. We also took care to mention enough accession names for the reader to obtain the encoding system used by the different programs. The arrows linking two accession names indicate their parental link. The arrows starting from the frame of a given program indicate the use of material of this program in another program or for creating a given breeding line. The number(s) in brackets indicate the literature reference where the information about the relationships between accessions and programs is provided. For the convenience of the reader, we summed up in Table 1

available information on the phenotype of the main resistant accessions lines displayed in Figure 1 and issued from the main historical breeding programs. Puerto Rico

Information about tomato breeding for bacterial wilt resistance in the University of Puerto Rico is very scarce and dispersed in annual reports of the Puerto Rico University Agricultural Experiment Station. For instance, Cook (1934, 1935), Roque (1935) and Theis (1950) mention partial resistance of some native material and its use in breeding. Warmke & Cruzado (1949) experimented with local selections from hybrids between native and imported tomato varieties, some of which showing some resistance to bacterial wilt and out-yielding the controls. Azzam (1964) reported the existence of resistance in S. pimpinellifolium as well as the development of breeding lines with some degree of resistance but with unacceptable fruit quality.

At the beginning of the 1960s, at Rio Piedras station, a double cross involving [„Platillo‟,( a native variety) X a S. pimpinellifolium, (of unknown identity)] X [a tomato, (of unknown identity) X „Platillo‟] was made by H. Azzam (Digat & Derieux, 1968; Daly, 1976) and its progenies were used by IRAT in the 1960s and 1970s [see below]. The literature also mentions „Beltville 3814 (=T414)‟ which was said to be from Puerto Rico and was used in North Carolina breeding effort [See below].

North Carolina The search and breeding of bacterial wilt resistant tomatoes began long ago in the

USA, at the turn of the 19th and 20th century in the agricultural experiment stations of several States including North Carolina, Florida, Alabama, and Mississipi (Kelman, 1953). After a lapse of years, efforts were resumed at the North Carolina Experiment Station in 1936 (Schmidt, 1936, 1937) and involved many horticultural scientists such as W.S. Barham, F.D. Cochran, M.E. Gardner, W.R. Henderson, J.S. Weaver, and plant pathologists such as D.E. Ellis, S.F. Jenkins, A. Kelman and N.N. Winstead (Henderson & Jenkins, 1972b). Warmke & Cruzado (1949) as well as Walter (1967) mention the existence of a US Southern Tomato Exchange Program (STEP) that was put into operation in 1946 (Yarnell, 1948), and was complemented with the National Screening Program for evaluation of PI (Plant Introduction) accessions of Lycopersicon for disease resistance. These programs are probably at the origin of the complex relationships between the breeding research carried out in North Carolina, Hawaii, Florida and Puerto Rico for bacterial wilt resistance.

The two widely mentioned sources of resistance of North Carolina breeding material are S. lycopersicum var. cerasiforme „PI 129080‟ (=T 702) from Colombia (initially classified as L. pimpinellifolium -Henderson & Jenkins, 1972b) and (ii) S. lycopersicum var. pyriforme „Beltsville No. 3814‟ (=T 414) (Henderson & Jenkins, 1972a & b; Laterrot et al., 1978; Hanson et al., 1998). „Beltsville No. 3814‟ also named „P.I. No. 3814‟ by Kelman (1953) originated in Puerto Rico according to this author and others (Winstead & Kelman, 1952; Henderson & Jenkins, 1972a & b) without further details. Thurston (1976) also said that it is a selection from Puerto Rico. However the name of this line and the fact that it has a PI number both suggest that „Beltsville No. 3814‟ was associated with the USDA, Beltsville (Maryland). Perhaps USDA researchers were collaborating with Puerto Rican researchers. „T414‟ displayed, as other bacterial wilt

9

resistant lines, a specific bitter taste with lasting burning sensation, and it was used by Borchers & Nevin (1954) for setting up a quantitative chemical test of the alkaloids responsible of this taste. Another source of resistance, S. lycopersicum „Mulua‟ from Guatemala, is mentioned by Winstead & Kelman (1952) and by Suzuki et al. (1964) [who refer to Winstead & Kelman (1952) as well as to a personal communication of D.E. Ellis]. According to Winstead & Kelman (1952), „Mulua‟ yielded resistant breeding material after an initial cross with „Rutgers‟. Suzuki et al. (1964, p.99) still referring to Winstead & Kelman (1952), mention also a „T-141‟ from Puerto Rico as another source of resistance used in North Carolina, though these latter authors mention „T414‟ and not „T-141‟. The identity of „T-141‟ is henceforth doubtful, either a mistyping of „T414‟ by Suzuki et al. (1964) or another line not reported in any other source we found.

To sum up, the cherry tomato „PI 129080‟ (=T 702) from Colombia, the pear shaped tomato „Beltsville No. 3814‟ (=T 414) and the tomato „Mulua‟ from Guatemala, have been included in NC breeding programs as genitors of bacterial wilt resistance.

„Venus‟ and „Saturn‟, released in the early 1970s (Henderson & Jenkins, 1972a & b) are the best known commercial varieties with resistance to bacterial wilt issued from the North Carolina State program. Their pedigrees are provided in Fig. 2, and their phylogenic relationship with two other NC lines, „MR4‟ and „NC 72 TR 4-4‟, is provided in Fig.3.

Hawaii D.C. McGuire, J.C. Gilbert and J.C. Acosta (breeders) as well as I.W. Buddenhagen

(pathologist) are among the scientists having worked on tomato resistance to bacterial wilt in the course of the 1950s and 1960s. Breeding for resistance in commercial type tomatoes was confined first (prior to 1955) to crossing root knot nematode resistant Hawaii lines and North Carolina bacterial wilt tolerant lines (Acosta et al., 1963, 1964). Acosta (1963) indicated that several North Carolina lines which had been bred for bacterial wilt resistance, proved to be intermediate in wilt susceptibility under Hawaiian conditions. In 1953 a new source of resistance, S. pimpinellifolium „PI 127805A‟, originating from Peru, was “obtained” [sic]5 and field selected in Hawaii through 9 generations (Acosta et al., 1964). This accession would be at the origin of the line „5808-2‟ (Mohanakumaran et al., 1967). Acosta (1963) writing the name as „HES 5808-2‟, mentions that it is an inbred line of L. pimpinellifolium obtained by D.C. McGuire, but he does not refer to any PI number. The commercial variety „Kewalo‟ (Fig. 4), developed by Gilbert et al. (1974), recombines the resistance to bacterial wilt originating from „PI 127805A‟ with root-knot nematode resistance(gene Mi) and other useful traits from „Anahu‟, a local tomato, and its derivative „Kalohi‟.

„Hawaii 7996‟ (H7996), „Hawaii 7997‟ (H7997) and „Hawaii 7998‟ (H7998) were later bred by J.C. Gilbert in the 1970s (Scott et al., 2005) and it has been reported in the literature (Hanson et al., 1998; Balatero & Hautea, 2001; Scott et al., 2005) that these lines had resistance derived from PI 127805A. However, correspondence dated October 1983 from J. Tanaka (Assistant Horticulturist at Hawaii University) to J. Scott indicates that the 3 mentioned Hawaiian lines and five others („H7975‟, „H7976‟, „H7981‟, „H7982‟, „H7983‟) are sister lines selected from a initially highly variable

5 The word “obtained” in this sentence is quite imprecise, since it might mean “received from someone” or

“obtained by breeding”.

accession named „HSBW‟, which acronym might mean „Hot Set Bacterial Wilt‟. This enigmatic accession, delivered to J.C. Gilbert via an unidentified way and planted first in 1973, displayed a high level of bacterial wilt resistance in hot tropical areas. An earlier correspondence, dated March 1978, from J.C. Gilbert to H. Laterrot (INRA) indicates that „Hawaii 7996‟ could be cited as having been selected at the University of Hawaii for bacterial wilt resistance, and as having its origin somewhere in the Philippines. J.C. Gilbert admitted in this letter that no publications had been specifically written for this line, and that he was not fully satisfied with it because of its flavour due to alkaloid residues in the ripe fruit. He recommended to using it as a rootstock or as a parent to be crossed with another parent of good flavour and some bacterial wilt resistance, for making F1s. Laterrot et al. (1978) also mentioned as a personal communication of Gilbert, a Philippine source at the origin of „Hawaii 7996‟. H. Laterrot recorded in his handwritten notes, based on Kaan personal communication, that „Hawaii 7996‟ was a selection made in „Hotset X Philippine tomato‟ and that it had very small fruits and a determinate growth habit. Given the absence of further written details, it is probably impossible to unravel further the pedigrees of „HSBW‟ and „Hawaii 7996‟.

In conclusion, a close look at the dispersed information relative to the breeding programs of Hawaii University indicates that several sources of resistance have been used successively there, first North Carolina material, then „PI 127805A‟ and lastly Philippines material. It is possible (or probable), that J.C. Gilbert recombined these sources along the time in his breeding material, in one way or another. Breeding is an art as much as a science, and the exact pedigree of the most famous bacterial wilt resistant line „Hawaii 7996‟ will probably remain the secret of the breeding genius of the late J.C. Gilbert.

Florida According to Sonoda et al. (1979) the first attempts to search for bacterial wilt

resistance in Florida started over one century ago, but the breeding efforts took a real momentum in the late 1970s. The original sources of resistance used were „Hawaii 7997‟, S. lycopersicum var. cerasiforme „CRA 66‟ and S. lycopersicum „PI 126408‟. The latter is one of the 28 PI accessions determined as resistant to bacterial wilt out of 909 accessions tested (Barham & Ellis, 1951). However most of the material derived in Florida utilized „Hawaii 7997‟. Attempts to pyramid resistance genes in the early 1980‟s were not successful as there were no molecular markers to identify the genes in resistant plants. No lines were developed that had resistance greater than any of the sources, so there was no evidence that improvements were made under Florida conditions. Over the years it was evident that it was difficult to attain large fruit with high resistance levels. In 1995 „Neptune‟ (Fig.5), a line with larger fruit size than „Hawaii 7997‟, was released, but its resistance level was less than that of „Hawaii 7997‟ (Scott et al., 1995a), and when tested in the world wide test (as Fla. 7421) „Neptune‟ also displayed a much narrower spectrum of resistance (Wang et al., 1998). Breeding efforts then focused on taking lines like „Neptune‟ and crossing them back to „Hawaii 7997‟ to attain large fruited lines with high resistance levels. At first, new lines were developed with moderate fruit size and high resistance. The next crosses were with very large fruited susceptible inbreds. From this work the sister lines „Fla. 8109‟ and „Fla. 8109B‟ were developed (Scott et al., 2003) and further crossing provided new inbreds with high

11

resistance and very large fruit (Scott et al., 2009). Hypothetically, „Fla. 8109‟ and the lines developed thereafter contain a resistance gene, missing in „Neptune‟, that was unlinked from a gene preventing large fruit formation, but this has not been elucidated yet.

Japan In Japan, development of bacterial wilt resistance in tomato (and eggplant) started

as early as 1951 and was based on the use of North Carolina lines. „OTB-1‟ and „OTB-2‟ are self pollinated offspring obtained in the 1950s respectively from „NC1953-60N‟ and „NC1953-64N‟ (Suzuki et al., 1964). According to later reports and papers published [in Japanese] by the Ministry of Agriculture and Forestry (H. Fukuoka6, pers. com.) „OTB-2‟ was segregating for several traits including bacterial wilt resistance (but was fixed for Fusarium wilt resistance) and was submitted to further screening for bacterial wilt resistance and further selfing. In 1969 „BF-Okitsu 101‟ was obtained7 from this process. „OTB1‟ and „OTB2‟ were described in 1964 by IRAT (French West Indies) as possessing the traits of the Puerto Rican S. pimpinellifolium, but with markedly bigger fruits and exceptional fruit productivity, together with a good behaviour towards viruses.

Philippines In Philippines, breeding was established as early as 1954 by T.L. York and J.R.

Deanon who evaluated local and foreign accessions with known resistance to bacterial wilt (Deanon, 1988). The exact origin of the resistance source(s) used in the Philippines breeding scheme is not found in the literature and hence remains confusing (Deanon, 1988; Wang et al., 1998). Empig et al. (1962) report some resistance in Philippine native material, such as „Los Baños native‟ which has possibly been used in the local breeding research. J. Acosta8 conducted research on the inheritance of tomato bacterial wilt resistance at the University of Hawaii (Acosta et al., 1964) and one can hypothesize (i) that he took Philippine material to Hawaii9 and conversely (ii) that he brought material back home (to the Philippines). North Carolina material entered Philippines breeding program according to Mew & Ho (1977). These authors, on the basis of a personal communication of J.R. Deanon, indicate that „Venus‟ (North Carolina line) entered the pedigree of the Philippine line „UPCA1169‟, together with a „CA64-1169‟ of un-mentioned origin (Figure 1). „UPCA1169‟ is itself at the origin of other Philippines material such as „VC8-1-2‟ and „VC9-1‟ (Mew & Ho, 1977; Wang et al., 1998; Scott et al., 2005). The origin(s) of the resistance of other valuable Philippine material, such as „TML46‟, „TML114‟, „R3034‟, or „HSBW‟ mentioned in the Hawaii section is not known.

Japan. 7 „BF-Okitsu 101‟ was obtained by A. Kotani, T. Kuriyama, H. Shimada-Mochizuki, S. Sakuma, and I.

Suzuki (H. Fukuoka, pers. com.). 8 According to http://www.tofil.ph/awardee_profile.php?id=78, J Acosta won a Rockefeller scholarship to

the University of Hawaii in 1958. This is also indicated in Acosta (1963). 9 This hypothesis is consistent with the information of Gilbert to Laterrot (Laterrot et al., 1978) that a

Philippine source had been used in Hawaii and is at the origin of „Hawaii 7996‟.

French West Indies (INRA & IRAT) and Burkina Faso (IRAT) In the French West Indies, the research on tomato bacterial wilt resistance started in

1963 at IRAT, and in 1964 at INRA, with some collaboration between the two institutes. According to Cordeil & Digat (1967) a collection from Rio Pedras station of the

University of Puerto Rico was introduced at IRAT Guadeloupe beginning of 1964. These authors mention a variable tolerance to bacterial wilt of some lines such as „199 PR‟, „Platillo 78‟ and L. pimpinellifolium under local conditions. „199 UPR‟, a derivative from the double cross made at Puerto Rico University [„Platillo‟ X S. pimpinellifolium] X [a tomato of unknown identity X „Platillo‟] -see above-, was chosen for its good tolerance to bacterial wilt (Daly, 1976). After pedigree selection, the F8 lines „199 UPR -39.15‟ and „199 UPR -39.16‟ were obtained by Daly (1976). These lines were described as having small watery and not fleshy fruits, with greenish gel around the seeds, and displaying many concentric cracks (IRAT, 1965; Cordeil & Digat, 1967). Both were crossed with „Floralou‟, a variety of good quantitative and qualitative yield in the conditions of the French West Indies (Cordeil & Digat, 1967; Digat & Derieux, 1968; Daly, 1976). After pedigree selection, the lines „IRAT L3‟ (Daly, 1976; Laterrot et al., 1978) -Fig.6- and „Farako-Ba‟ (D‟Arondel de Haye, unpubl., IRAT, 1974, 1975; Laterrot et al., 1978; Rouamba et al., 1988) were respectively obtained in Martinique and Burkina Faso.

The INRA program in Guadeloupe was based on the use of „CRA66‟. The origin of this line is still controversial. It is given by Digat & Derieux (1968) and Anaïs (pers. com.) as one of the many small fruited tomato ecotypes grown in Guadeloupe at that time, and known there as „tomadoses‟. Digat & Derieux described „CRA66‟ as a vigorous line bearing small, pink, and bitter fruits with resistance to bacterial wilt. However another origin of CRA66 is suggested by Kaan (pers. com.) as being „OTB2‟, because the phenotype of „CRA66‟ is very different from the phenotype of the tomadoses: the plant is more vigorous, the leaves have a spreading leaf growth habit, the flowers display an exerted style, the fruits are fasciated and although of pink colour, they have a larger size than tomadoses fruits. There is a green gel inside the fruit, the taste of which is more acrid and extremely bitter, and its bacterial wilt resistance level is higher. However, Suzuki et al. (1964) reported „OTB1‟ was pink fruited, whereas they described „OTB2‟ as red fruited (but segregating for several traits). As IRAT experimented in Guadeloupe „OTB1‟, „OTB2‟ and many other bacterial wilt resistant lines in the mid- 1960s (IRAT 1964, 1965), it is plausible that valuable material „reached‟ INRA by some path and perhaps under a distorted identity for some reason. If „CRA66‟ = „OTB2‟, then all the French West Indies material would derive indirectly from North Carolina material -see Fig. 1-. Comparison of molecular fingerprinting of „OTB2‟ and „CRA66‟ is necessary for elucidating the identity of these two lines.

Crosses started in the 1960s between „CRA66‟ and the susceptible commercial type „Floradel‟ resulted in the varieties „Cranita‟ (Fig.7), „CRA74‟ & „Carette‟ (Fig. 8 & 9), and „Caraibo‟ (= „Caraibe‟) -Fig. 9- that were respectively released in 1971, 1973, 1975, and 1980 (Anaïs, 1986, Anaïs 1997). „CRA84-26-3‟ and „Caravel‟ are offspring of the cross [„Caraibo‟ X „HC8‟] where „HC8‟ is a heat-tolerant and bacterial wilt resistant line derived from the cross „Hawaii 7996‟ x „Campbell 28‟. Later on „Caraibo‟, „HC8‟ and „Caravel‟ were used as genitors in a recurrent selection for recombining their bacterial wilt

resistance and agro-climatic adaptation to French West Indies conditions, together with resistance to Begomoviruses (Ano et al., 2002; Ano et al., 2004).

Taiwan AVRDC started tomato breeding in 1972, and from 1973-1980 emphasized the

development of breeding lines with heat-tolerance and bacterial wilt resistance (Opena et al., 1989). Sources of BW resistance frequently used as parents in AVRDC breeding included varieties „Venus‟ and „Saturn‟ from North Carolina State University and lines „VC 11-3-1-8‟, „VC 8-1-2-7‟, „VC 48-1‟ from the University of the Philippines. Most AVRDC bacterial wilt resistant lines developed in the 1970‟s such as „CL8d-0-7-1‟ (derived from „VC11-1-2-1B‟ x „Venus‟), „CL9-0-0-1-3‟ (derived from „VC11-1-2-1B‟ x „Saturn‟), and „CL11d-0-2-1‟ (derived from „VC9-1-2-9B‟ x „Venus‟) were bred from crosses of these two sources. Many AVRDC lines developed in the late 1970‟s and early 1980‟s such as „CL1131‟, „CL5915‟ (Fig.10), and „CLN65‟ (Fig. 11) arose from complex crosses involving North Carolina, Philippines, or AVRDC lines with BW resistance derived from the above sources. High levels of BW resistance were detected in „L285‟, a small-fruited S. lycopersicum germplasm accession from Taiwan (Chang #1) but this source was not used at AVRDC in breeding because it was thought that its bacterial wilt resistance and small fruit size were closely associated (Opena et al., 1992). In 1985 AVRDC received resistant lines developed in Guadeloupe, including „CRA84-58-1‟ and „CRA84-26-3‟, that combined BW resistance and large fruit size. CRA lines were crossed to heat tolerant and BW resistant AVRDC lines which led to the development of AVRDC lines „CLN1462‟, „CLN1463‟ (Fig.12), „CLN1621‟, „CLN2026‟, and many others.

2. Limit of the reliability of the survey: insufficient accuracy of the information The information found in the literature is often vague and sometimes inconsistent

between publications. The absence of published pedigrees for many of the important varieties resistant to bacterial wilt is a real impediment for ascertaining the original sources of their resistance. Henceforth, Figure 1 is the result of our interpretation of sometimes blurred information as exemplified below.

Names of the accessions Depending on the publications, the accessions used in the various trials or breeding

programs are not exactly named the same way. This is due in some cases to probable renaming such as for „199 PR‟ (Cordeil & Digat, 1967), which is also found as “199” (Digat & Derieux, 1968), „199 UPR‟ (Daly, 1976), and „UPR 199‟ (Kaan et al., 1969). The same situation is encountered for „P.I. No. 3814‟ (Kelman, 1953), also found as „Beltsville #3814‟ (Henderson & Jenkins, 1972a; Hanson et al., 1998), „Beltsville No. 3814‟ (Henderson & Jenkins, 1972b), and „Beltsville 3814‟ (Laterrot et al., 1978). However other variations of names such as for „H7997‟ also found as „H7997S‟ and „H7997L‟, „H7998‟ also found as „H7998S‟ and „H7998M‟, or „CRA66‟ found as „CRA66P‟ and „CRA66S‟ in Wang et al. (1998) and Scott et al. (2005) do not mean further selections but encode only the name of the person who provided the seeds used in the trials. These latter authors mention „BF-Okitsu‟, otherwise found as „BF-Okitsu 101‟ in Laterrot (1999).

14

Despite the word “Okitsu” (location in Japan where breeding was carried out, H. Fukuoka, pers. com.) is present in the names of bacterial wilt resistant „BF-Okitsu 101‟ and of bacterial canker resistant „Okitsu Sozai n°110 (Kuriyama & Kuniyasu, 1974), these accessions should not be confused with each other.

Contradictory data found in the literature Apart from the controversy concerning the identity of „CRA66‟, other contradictory

information is found in the literature. Particularly in the case of „Hawaii 7996‟and the other Hawaii 79## accessions, resistance was said to originate from a Philippines accession according to several personal communications between breeders in the 1970s, but according to Acosta et al. (1964) „PI 127805A‟ and North Carolina material are at the origin of the resistance to bacterial wilt of Hawaiian material. It is not possible to reconcile these conflicting statements other than to say that the various sources of resistance were introduced to the Hawaiian program over time. Therefore we left all options on Figure 1.

Unclear origin of some accessions We found no original information on the origin or pedigree of „Beltsville 3814‟ and

further search of 1960s and 1970s publications of Beltsville USDA research station is needed. Another case concerns the unclear relationship between the Peruvian S. pimpinellifolium „PI 127805‟ collected in 1938 and maintained by the USDA Northeast Regional PI Station and „PI 127805A‟ obtained in 1953 and field selected for resistance through 9 generations in Hawaii according to Acosta et al. (1964). Furthermore, „5808-2‟ was derived from „PI 127805A‟ according to Mohanakumaran et al. (1967) but is given as an inbred line of an anonymous L. pimpinellifolium according to Acosta (1963).

Likeness between accessions Phenotypically „BF-Okitsu‟ is very close to „Hawaii 7998‟ (J. Scott and J. Wang, pers.

obs.), though the published information (Fig.1) does not indicate a closer relationship than the presence of North Carolina material in both their pedigrees. Comparison of their molecular fingerprinting would be worthwhile to clarify their genetic relationship.

3. Sources of resistance and inheritance patterns The global survey of the major breeding research for tomato bacterial wilt resistance

points out that the main sources of resistance used worldwide are perhaps only half a dozen accessions of S. pimpinellifolium („PI 127805A‟), S. lycopersicum var. cerasiforme („PI 129080‟), S. lycopersicum var. pyriforme („Beltsville 3814‟), a progeny from a cross between a S. pimpinellifolium and S. lycopersicum („199 UPR‟), S. lycopersicum („Mulua‟) and the enigmatic Philippine accession used in Hawaii in the 1970s. This number could be extended to seven accessions if one adds „CRA66‟ by assuming it is a Guadeloupe tomadose and not a progeny from „OTB2‟. Whether there are 6 or 7 main sources of resistance, the genetic basis of tomato resistance mechanisms used worldwide for breeding is quite narrow. North Carolina material has been integrated in most of the other breeding programs, in particular those of Hawaii, Japan, Philippines and Taiwan. By combining NC material, or not, with other sources of

10 „Okitsu Sozai n°1‟ resistance to Clavibacter michiganensis (formerly named Corynebacterium michiganense) originates from S. habrochaites (L. hirsutum var.

glabratum) „PI 134418‟.

resistance, and breeding in geographical areas where different strains of bacterial wilt are prevalent, the breeders exploited the genetic potentialities at their disposal, and created material resisting a wide range of bacterial wilt strains as exemplified by the results obtained in the worldwide trial carried out by Wang et al. (1998). Indeed, the top nine resistant accessions which had high levels of resistance in almost all 12 locations tested (>90% survival on average) were developed in Hawaii („H7996‟, „H7997 S and L‟, „H7998 S and M‟), Philippines („TML46‟ and „TML114‟, „R3034‟), and Japan („BF-Okitsu‟).

Other sources of resistance in wild tomatoes have been described sporadically in

the literature in accessions of the same species (S. pimpinellifolium, cherry and pear S. lycopersicum) as well as in other wild relatives of tomato (Laterrot & Kaan, 1977; Jaworski et al., 1987; Anaïs, 1997; Mohamed et al., 1997; Carmeille et al. 2006b; Hai et al., 2008). From these results, it seems that resistance to bacterial wilt is not that frequent in tomato germplasm. The high genetic diversity displayed by Ralstonia solanacearum complex (Fegan & Prior, 2005) and the strong interactions between strains and resistant material (Lebeau et al., 2011) suggest that various resistance mechanisms, including strain specific ones, exist in tomato resistant germplasm. Therefore, breeders have some opportunities at their disposal to enlarge the relatively narrow range of resistance sources primarily used so far, and to continue accumulating different mechanisms of resistance in tomato genotypes to obtain better stability of resistance in different environments. However, they might be limited by the fact that some bacterial strains are not controlled by any resistant accession (see section 5. below).

Inheritance studies have focused mostly on F2, F3 and RILs progenies of „Hawaii

7996‟ crossed with the susceptible „WVa700‟ (S. pimpinellifolium). Several QTLs of resistance have been identified, including a major QTL on chromosome 6 effective towards „GMI8217‟, an isolate of race 1 biovar 1 (Thoquet et al. 1996a & b); of „Pss4‟, an isolate of race 1, biovar 3, phylotype 1 (Wang et al., 1998); and „JT516‟, an isolate representative of race 3-phylotype II (Carmeille et al., 2006a). Wang et al. (2000) identified another major QTL of resistance of „Hawaii 7996‟ effective towards „Pss4‟ and located on chromosome 12. Several minor QTLs located on chromosomes 3, 4, 8, some of which having a season dependent expression (Carmeille et al., 2006a) have also been identified. Mejia et al (2009) confirmed the QTLs on chromosome 6 and 12 were associated with resistance in „Hawaii 7996‟ observed in Guatemala field evaluation against local phylotype I strains. Work is ongoing at AVRDC for adding markers to the QTLs regions of „Hawaii 7996‟ associated to resistance to bacterial strains belonging to phylotype I, in order to develop tools for marker assisted selection.

QTLs of resistance of the resistant line „L285‟ effective towards „UW364‟ an isolate of race 1, biovar 4, have also been located on chromosomes 6, as well as on chromosomes 7 and 10 (Danesh et al., 1994). Pattern of resistance derived from CRA66 has been described as polygenic (Prior et al., 1994) but no molecular data are available for this source.

16

4. Resistance to bacterial wilt is sometimes associated to resistance to other

bacterial and fungal pathogens Kaan & Laterrot (1977) were the first to mention a quantitative resistance to

Fusarium wilt (Fusarium oxysporum f.sp. lycopersici) race 2 in lines bred for bacterial wilt resistance in Puerto Rico, North Carolina, and the French West Indies and they suggested this relation to be more likely of a pleiotropic nature than being due to a genetic linkage. Further, Laterrot & Kaan (1978) as well as Laterrot et al. (1978) have pointed out the frequent association of both these partial resistances with the partial resistance to a third vascular disease, i.e. bacterial canker caused by Clavibacter michiganensis. These authors exemplified this relation between the resistance to the three diseases on a set of varieties bred for bacterial wilt in North Carolina („NC 72 TR 4-4‟, „MR4‟, „Venus‟ and „Saturn‟), in the French West Indies („Carette‟, „53 RC‟, „IRAT L3‟), in Burkina Faso („Farako-Ba‟), and in Hawaii („Hawaii 7996‟). They checked that the resistance to Fusarium wilt race 2 observed was not due to the gene I-2. „Kewalo‟ was the only variety resistant to bacterial wilt that they found susceptible to bacterial canker, and of a low level of resistance to Fusarium wilt race 2. This exception suggests that the mechanisms controlling the resistance to bacterial wilt can be dissociated, in some genotypes, from those involved in the resistance to the two other vascular diseases. Unfortunately Laterrot & Kaan (1978) and Laterrot et al. (1978) did not test bacterial wilt resistant material created in the Philippines and Taiwan, and the general picture of the relationships between the resistance to bacterial wilt and the two other vascular diseases is incomplete.

The reciprocal relationship between the resistance to bacterial canker and the two other diseases is verified in some cases, as for instance for „Okitsu Sozai n°1‟ whose resistance to bacterial canker originates from S. hirsutum var. glabratum PI 134418. This line is also partially resistant to Fusarium wilt race 2 (Laterrot, unpub. results) as well as to some strains of Ralstonia solanacearum (Lebeau et al., 2011). But „Plovdiv 8-12‟, the resistance of which to bacterial canker originates from a S. pimpinellifolium, is susceptible to Fusarium wilt race 2 (Laterrot et al. 1978); its behaviour towards bacterial wilt is unknown.

The bacterial wilt resistant „Hawaii 7998‟ was resistant to a race of bacterial spot

later confirmed to be race T1 (Scott & Jones 1986). Later, Scott et al (1995b) discovered „Hawaii 7981‟, a line susceptible to race T1, was resistant to bacterial spot race T3 while „Hawaii 7998‟ was susceptible. Thus, bacterial spot resistance has been found in bacterial wilt resistant lines from Hawaii. For race T1, resistance to bacterial wilt was not correlated with bacterial spot resistance in an F2 population suggesting separate genes were responsible for resistance to each disease (Scott et al., 1988). Resistance to bacterial spot race T4 has been seen in some bacterial wilt resistant breeding lines derived from „Hawaii 7997‟ even though this line is not resistant to race T4 (Scott et al., 2010). The genetic control of this response is not known but again illustrates the association of bacterial wilt resistance with resistance to another disease. A further example is that „Hawaii 7998‟ had resistance to bacterial canker (Panthee and Gardner, 2010) especially the foliar phase. These examples and those mentioned before indicate the existence of frequent associations between the resistance to some

17

bacteria (vascular or not) and even fungi (vascular) within single tomato genotypes. Hence, Scott (1997) advised that when searching for resistance to a given bacterial pathogen, breeders should not overlook genotypes resistant to other bacteria. In this regard, resistance genes can emerge by combining genotypes with some reported bacterial resistance even when one of the parent lines does not show resistance to a particular disease/race. For instance, Hutton et al. (2010) reported that an allele from „Hawaii 7998‟ was associated with resistance to bacterial spot race T4 even though this line was susceptible to race T4, suggesting epistasis with genes from the other parent that was T4 resistant. Another possibility is that the pleiotropic nature of resistance in tomato against several diseases could be associated with higher level of expression of systemic acquired resistance (SAR). Lin et al (2004) found over-expression of Arabidopsis NPR1 (non-expresser of PR genes) gene in a susceptible tomato line could enhance resistance to both Fusarium wilt race 2, bacterial wilt, as well as bacterial spot and gray leaf spot. In this study, they did not test the enhanced resistance against the bacterial canker pathogen.

Lastly, Rouamba et al. (1988) tested material resistant to bacterial wilt towards a

fourth vascular disease, the Verticillium wilt caused by Verticillium race 2, but they found only a loose relationship between both resistances since only two („IRAT L3‟ and „Farako-Ba‟) out of ten lines tested, were resistant to both diseases.

5. Grafting of susceptible cultivars on resistant rootstocks, an alternative to resistant cultivars

Given the difficulty to create highly resistant lines with good commercial quality, grafting susceptible scions on resistant rootstocks remains an alternative to the cultivation of resistant cultivars. As early as 1969, Gilbert and Chin pointed out that highly resistant tomato lines with poor fruit quality, could be efficiently used as rootstocks on which susceptible scions of good fruit quality could be grafted. These authors reported the bacterial wilt resistance of the root system as being effective even when completely susceptible scions are used. This technique is still used nowadays (Cardoso et al., 2006; Wang et al., 2009), though the protection provided by the rootstock is sometimes incomplete (Nakaho et al., 2004). Indeed, tomato resistant material harbours the bacteria symptomlessly and the resistance is associated with the ability of the plant to restrict bacteria invasiveness (Grimault et al., 1993). The absence of incompatible interactions in tomato resistant lines (no symptoms, no latent infection) has been confirmed by Lebeau et al. (2011) by testing a core collection of bacterial wilt resistant accessions with a core collection of bacterial strains.

Eggplant is an alternative rootstock for cultivating susceptible tomatoes in contaminated conditions. It was shown to provide a better protection than tomato rootstocks (AVRDC, 1998). This result was confirmed and extended by Lebeau et al. (2011) who found that apart from common cases of latent infection for some eggplant accessions and all tomato accessions, there also exist incompatible interactions between some eggplant resistant lines and some bacterial strains. Further, some eggplant lines control bacterial strains that are not controlled by any of the tomato resistant lines tested so far, as exemplified by Carmeille et al. (2006b), Wicker et al. (2007) and Lebeau et al. (2011).

18

Conclusion The earliest breeding efforts for tomato resistance to bacterial wilt started in Puerto

Rico and two American States (North Carolina, Hawaii) 80 years ago followed by programs in the 1950s in Japan and the Philippines. The programs carried out by French research institutes in the Caribbean (and Burkina Faso) started during the course of the 1960s, whereas AVRDC started at the beginning of the 1970s. There were many exchanges of material between the breeding programs for bacterial wilt resistance carried out in several US States, and between them and the Philippines. AVRDC is using and recombining now the resistances bred in the USA, the Philippines and the French West Indies. The breeding material created in Japan was mostly used locally, and perhaps also in Guadeloupe, if one assumes that the Japanese line „OTB2‟ is equivalent to „CRA66‟, which is not certain.

Our attempt to draw a general picture of the main sources of resistance to bacterial wilt, of the main breeding programs for this resistance, of their most frequently mentioned resistant varieties, and of the relationships between varieties, is based on a careful work of assembling bits and pieces dispersed in many publications. Given the unavailability of complete information, it is not now possible to come up with a better picture than the one we present here, though more information can emerge out of archives of the scientists, Universities and research institutes involved. Henceforth the synthesis provided here displays the most probable general picture, but it may include some mistakes in the absence of further information.

We added to this survey complementary information on some peculiarities of tomato bacterial wilt resistance. The frequent association of bacterial wilt resistance with resistance to other bacterial or fungal diseases should be of strong interest for breeding and/or research on its genetic basis. Breeding over many decades succeeded in eliminating a number of undesirable traits initially associated to high level of bacterial wilt resistance, but breeding efforts are still ongoing for obtaining large fruit size in resistant material. The adaptation of the breeding material to hot environmental conditions is often mentioned as necessary for obtaining breeding lines which are resistant and agronomically acceptable.

On the whole, we hope this paper to be useful for further research using the plant material mentioned, in particular for comparative genetic studies and breeding concerning the resistance of tomato to bacterial wilt and to other vascular diseases.

Research Papers TGC REPORT VOLUME 60, 2010 Preliminary Observations on the Effectiveness of five Introgressions for Resistance to Begomoviruses in Tomatoes Luis Mejía, Rudy E. Teni, Brenda E. García, Ana Cristina Fulladolsa, and Luis Méndez, Facultad de Agronomía, Universidad de San Carlos de Guatemala; Sergio Melgar, Escuela de Biología, Universidad de San Carlos de Guatemala and Douglas P. Maxwell, Department of Plant Pathology, University of Wisconsin-Madison Introduction: Tomato-infecting begomoviruses have remained a major constraint to tomato production in many parts of the tropical and sub-tropical regions. Management strategies have involved i) extensive use of insecticides to control the whitefly vector, Bemisia tabaci, ii) production of virus-free transplants, iii) host-free periods, iv) use of whitefly-proof fabric cover in micro- and macro-tunnels for 30 or more days, and v) use of moderately resistant hybrids. Over the past decade the availability of moderately resistant hybrids has increased and most private seed companies devote resources to the incorporation of begomovirus-resistance genes into their new generation of hybrids.

Several genes for resistance to begomoviruses have been identified in the last two decades (Ji et al., 2007). Zamir et al. (1994) described the first resistance gene, Ty1, originating from the wild species Solanum chilense accession LA1969, to a region located between 4 cM and 10 cM in the short arm of chromosome 6. Later, gene, Ty2, was incorporated into the genome of the tomato from the wild species Solanum habrochaites by Hanson et al. (2000) and the introgression was located between 84 and 91 cM in chromosome 11. More recently, Ji et al. (2007b) reported gene, Ty3, in an introgression derived from S. chilense accession LA2779 and located at 19 to 25 cM in chromosome 6. An introgression in this same region from S. chilense accession LA1932 was designed Ty3a (Ji et al., 2007a). The resistant lines from the accession LA1932 had yet another gene, Ty4, which was recently located in the upper half of chromosome 3 (Ji et al., 2008) near 82 cM (Maxwell, personal communication). A major QTL, Ty5, was recently mapped in the TY172 breeding line with introgressions from S. peruvianum from approximately 16 to 46 cM on chromosome 4 (Anbinder et al., 2009). The potential for pyramiding begomovirus-resistance introgressions from different accessions of S. chilense, from different wild species such as S. peruvianum or S. habrochaites was discussed by Vidavski et al. (2008). Using several sources of resistance in one hybrid may overcome the selection of virus variants with novel genome combinations that may be more aggressive on tomatoes with one begomovirus-resistance introgression (García-Andrés et al., 2009). Because of the need to understand how different resistance genes respond to begomoviruses, this project was initiated to evaluate the effectiveness of begomovirus-resistance introgressions (Ty1, Ty2, Ty3, Ty3a, and Ty4) for conferring resistance to begomoviruses in a field trial in Guatemala. It is expected that this information will

42

provide a rationale for pyramiding begomovirus-resistance introgressions into hybrids that will have more durable resistance. Materials and Methods:

Germplasm: The breeding lines used in these experiments were: Gh13, homozygous for Ty3; Gc143-2, homozygous for Ty1 and Ty3; Gc171, homozygous for Ty3a and Ty4 (provided by J. Scott, University of Florida); CLN2116 homozygous for Ty2 (provided by P. Hanson, The World Vegetable Center) and Gh188-2, also homozygous for Ty2, and Gc21-a, homozygous for Ty3a and lacking Ty4. Gh13 was selected from the hybrid, Favi9 (Vidavsky and Czosnek, 1988). Gc143-2 was selected from a cross of Gc9 (provided by J. Scott, University of Florida) by a susceptible commercial hybrid. Gc21-a was obtained by several cycles of selfing from a cross between Gc171 with a susceptible commercial hybrid and an individual F2 plant. Gh188-2 was selected from a commercial hybrid with Ty2 introgression. The susceptible germplasm, HUJ-VF, without any of the introgressions for resistance, was used in several crosses. HUV-VF was provided by F. Vidavsky, The Hebrew University of Jerusalem. The F2 population used in the segregation of genes Ty3a and Ty4 was obtained from a hybrid produced by a cross between the resistant line Gc171 and a slightly resistant inbred (Gh44).

PCR Methods for detection of the introgressions associated with resistance to begomoviruses: DNA extraction was as reported by García et al. (2008). PCR-based molecular markers have been developed for the detection of Ty2, Ty3, Ty3a, and Ty4. Garcia et al. (2007) developed a co-dominant SCAR (Sequence Characterized Amplified Region) marker from the RFLP T0302 marker at 89 cM for the detection of the Ty2 introgression. The Ty3 and Ty3a introgressions were monitored with the co-dominant SCAR marker P6-25 (Ji et al., 2007a). The Ty4 introgression was detected with PCR primers developed by Y. Ji and J. Scott (personal communication, Ji et al., 2008). The presence of the Ty1 introgression in Gc143-2 was determined by sequencing the PCR fragments associated with the RFLP TG97 marker (García and Maxwell, unpublished). Field Evaluation of disease severity for the different populations: Each entry was replicated three times with 5 plants per replication. Four-week-old seedlings were transplanted into a field near Sanarate, Guatemala, where high levels of viruliferous whiteflies were present. In this area, at least 7 bipartite tomato-infecting begomoviruses have been identified (Nakhla et al., 2004) as well as the monopartite begomovirus, Tomato yellow leaf curl virus (Mejía and Maxwell, unpublished results). Each plant was scored at about 30-days after transplanting in either January 2009 or October 2009 using a disease severity index (DSI) from zero to six: 0, no symptoms; 1, extremely slight symptoms; 2, slight symptoms; 3, moderate symptoms; 4, severe symptoms with deformed leaves; 5, severe symptoms with stunted plant; and 6, very severe symptoms, no marketable fruit and very stunted plant.

Development of populations with different introgressions: Combinations of introgressions Ty3a and Ty4: An F2 population was obtained

from a F1 hybrid produced from the cross between line Gc171 (Ty3a/Ty3a, Ty4/Ty4, Scott and Schuster, 2007) by a slightly resistant line (Gh44, ty3/ty3, ty4/ty4). Leaf samples were collected from 77 individual plants for molecular analysis. The genotype of these plants was determined with the PCR primers P6-25F2 and P6-25R5 (SCAR marker P6-25) for introgression Ty3a and a PCR-based marker for Ty4 introgression (Ji et al., 2008). Individual F2 plants were selected that were dominant for one or both genes (RR, Ty3a/Ty3a, Ty4/Ty4; RS, Ty3a/Ty3a, ty4/ty4; SR, ty3/ty3, Ty4/Ty4 and SS, ty3/ty3, ty4/ty4). These plants were selfed to produce F3 seeds. Twelve F3 families, Gc171, Gh44 and a susceptible commercial control C-SS (ty3/ty3, ty4/ty4) were planted in a field to determine their phenotype, i.e., the level of resistance to begomoviruses was determined in January 2009. Each entry was replicated three times with 5 plants per replication.

Combination of introgressions for Ty2 and Ty3: F2 seed was obtained from the cross between resistant line Gh13 (Ty3/Ty3, ty2/ty2, RS-C, Martin et al., 2007), and line CLN2116 (ty3/ty3,Ty2/Ty2, SR-C). The genotype of the F2 plants was determined using molecular markers and individuals with one, both or none of the introgressions for resistance (genotypes RR, Ty3/Ty3,Ty2/Ty2; SR, ty3/ty3, Ty2/Ty2; RS, Ty3/Ty3, ty2/ty2 and SS, ty3/ty3, ty2/ty2) were allowed to self. The genotype of each F3 family was verified and seventeen F3 families were transplanted into a field along with the two parental lines and a susceptible control. Each entry was replicated three times with 5 plants per replication to determine their phenotype and DSIs were taken in October 2009.

Combination of introgressions Ty1, Ty3 and Ty2: F2 seed was obtained from the cross between resistant line Gc143-2 (Ty1/Ty1-Ty3/Ty3, ty2/ty2) and line Gh188-2, (ty1/ty1-ty3/ty3, Ty2/Ty2). The genotype of the F2 plants was determined using molecular markers for Ty3 and Ty2 and individuals with one, both or none of the introgressions were identified (RR, Ty3/Ty3, Ty2/Ty2; RS, Ty3/Ty3, ty2/ty2; SR, ty3/ty3, Ty2/Ty2 and SS, ty3/ty3, ty2/ty2). The Ty1 introgression was not determined as it is linked to Ty3. F3 seed was collected from individual F2 plants of different genotypes and the F3 families were transplanted in the field. Sixteen F3 families and both parental lines were planted and each entry was replicated three times and 5 plants per replication. Plants were scored for their DSIs in October 2009.

Combination of introgressions Ty3a and Ty2: Gc21-a (RS, Ty3a/Ty3a, ty2/ty2), was crossed with line Gh188-2 (SR, ty3/ty3, Ty2/Ty2). Heterozygous individuals were evaluated for resistance (HH, Ty3a/ty3, Ty2/ty2), along with the parental genotypes. Gc21-a (RS) and Gh188-2 (SR) were also crossed to the susceptible line HUJ-VF (ty2/ty2, ty3/ty3). The genotypes of the F1 populations were verified and their resistance phenotype determined in the field in October 2009. Three hybrids [Gc21-a X Gh188-2 (HH, Ty3a/ty3, Ty2/ty2), Gc21-a X HUJ-VF (HS, Ty3a/ty3, ty2/ty2) and Gh188-2 X HUJ-VF (SH, ty3/ty3, Ty2/ty2)], two parental lines and a susceptible commercial control (SS) were planted with three replications of 5 plants each. Plants were scored for their DSIs in October 2009.

Combination of introgressions Ty3a and Ty3: Line Gc21-a (Ty3a/Ty3a) was crossed with line Gh13 (Ty3/Ty3). The level of resistance in the hybrid (Ty3a/Ty3)

44

was evaluated in relation to the parental genotypes. The genotype of the F1 families was determined and subsequently transplanted in the field for the evaluation of their phenotype of resistance. The hybrid (Gc21-a X Gh13), both parental lines, and a susceptible control were planted in with three replications of five plants each. Plants were scored for their DSIs in October 2009. Results and Discussion: Natural inoculation with begomoviruses in a field in Guatemala with high populations of the whitefly vector was used to evaluate various combinations of begomovirus-resistance introgressions for their effectiveness to provide resistance to multiple begomoviruses. Evaluations of the introgressions Ty3a and Ty4: The highly resistant inbred line, Gc171 (Ty3a/Ty3a, Ty4/Ty4), was crossed with a slightly resistant genotype (Gh44, ty3/ty3, ty4/ty4) (Garcia, et al., 2008a). Among the 77 F2 plants analyzed, 17 were found to be homozygous Ty3a/Ty3a, 12 homozygous ty3a/ty3a, and 48 heterozygous Ty3a/ty3a. With relation to Ty4 introgression, 10 plants were found to be homozygous Ty4/Ty4, 42 homozygous ty4/ty4, and 25 heterozygous Ty4/ty4. Seven F3 families were evaluated: three with genotype ty3/ty3, Ty4/Ty4 (SR), and four with genotype Ty3a/Ty3a, ty4/ty4 (RS) (Fig. 1).

The average DSI for the RS F3 families with the Ty3a introgression was 2.1, while the SR F3 families with the Ty4 introgression was 3.6, which is similar to the slightly resistant parent, Gh44 (S-SS). These results indicate that there is a larger effect on resistance by Ty3a than by Ty4 to the multiple bipartite begomoviruses present in this area. This is consistent with the report by Ji et al. (2008) where the Ty4 introgression had a lesser effect on resistance to Tomato yellow leaf curl virus than the Ty3a introgression.

Combinations of introgression Ty2 and Ty3: Seventeen F3 families were obtained from individual F2 plants arising from the cross of Gh13 X CLN2116 (F1, Ty3/ty3, Ty2/ty2). The F3 families were evaluated for symptom development 36 days after transplanting (Fig. 2).

The parents had average DSIs of 0.6 and 3.8 for Gh13 and CLN2116, respectively. A commercial hybrid with neither introgression had a DSI of 5.2. The average DSI of the 6 RR families was 1.6, which was greater than the most resistant parent, Gh13 (DSI 0.6), and was similar to the DSI for the 3 RS families, which had an average DSI of 1.4. The average DSI of the 5 SR families (DSI 2.9) was similar to that for the 3 SS families (DSI 2.6).

These results indicate that Ty3 introgression from Gh13 was mainly responsible for the observed level of virus resistance in the F3 families and adding the Ty2 introgression resulted in no increase in virus resistance. The susceptible control had a DSI of 5.1, while the 3 F3 families without the introgressions (ty3/ty3, ty2/ty2) had a DSI of 2.6, indicating the presence of other unknown genes for resistance. Of interest was the range of average DSIs within families of one genotype (Fig. 3). For the 6 RR families, the average DSI ranged from 0.8 to 2.3. For the 3 SS families the range was also great, 1.8 to 3.6, for the 3 RS the range was 1.1 to 1.9. For the 5 SR families the range was 2.1 to 3.2. One explanation for these differences among F3 families with the same genotype for the two introgressions could be that there was segregation of other modifying resistance genes in the F2 plants used to generate the F3 families.

Combination of introgressions Ty1-Ty3 and Ty2: Individual F2 plants of different genotype obtained from the F1 (Ty1-Ty3/ty1-ty3, Ty2/ty2) of the cross of Gc143-2 X Gh188-2 were selfed to produce 16 F3 families. The DSI for these families was determined in the field (Fig. 4).

The average DSI for RS families with the T1-Ty3 introgression was 1.7 while DSI for those SR families with the Ty2 introgression was 4.8. RR families with both introgressions for resistance had an average DSI of 1.4 and those with neither introgression had DSI of 3.6. There was no difference in the average DSI for the RR and SR families. Surprisingly, the DSI for the SR families was higher than the DSI for the SS families. These observations indicated that Ty2 introgression provides no effective resistance to these begomoviruses.

An important observation was that there was a considerable range in the average DSI for families with the same genotype for these two introgressions (Fig. 5). For example, one RR family had a DSI of 3.2, which was greater than the other four RR families (range of 0.3 to 1.4). Within the RS families, one family had a DSI of 0.2 and another RS family had a DSI of 3.8. The genotype for the markers in these families, i.e., the presence or absence of the PCR fragments corresponding to the S. lycopersicum size or the introgression size, was reconfirmed by additional testing in the laboratory. Explanations to consider are that there could have been a recombination event between the PCR marker and the resistance gene for these introgressions or that other genes controlling resistance were segregating within the F2 plants.

Combinations of genes Ty3a and Ty2: Line Gc21-a (DSI 0.7), homozygous for Ty3a, was crossed to line Gh188-2 (DSI 5.2), homozygous for Ty2; and the DSI for the F1 (HH, Ty3a/ty3, Ty2/ty2) was 0.4. Lines Gc21-a and Gh188-2 were also crossed with susceptible line HUJ-VF (ty3/ty3, ty2/ty2). The resulting heterozygous F1‟s, Ty3a/ty3, ty2/ty2 (HS) and ty3/ty3, Ty2/ty2 (SH) had DSIs of 2.9 and 4.2, respectively (Fig. 6). Thus, the Ty2 gene along either in a homozygous or heterozygous condition did not confer an adequate level of resistance. The Ty3a introgression in the heterozygous condition conferred a moderate level of resistance, but when both resistance introgressions were present in the heterozygous condition the F1 was highly resistant.

Average disease severity index (DSI) and standard errors for the heterozygous genotypes HH (Ty2/ty2, Ty3a/ty3), SH (ty3/ty3, Ty2/ty2), HS (Ty3a/ty3, ty2/ty2) and homozygous parental lines RS (Ty3a/Ty3a, ty2/ty2), SR (ty3/ty3, Ty2/Ty2), and susceptible commercial control SS (ty2/ty2, ty3/ty3).

These results indicate that the combination of introgressions Ty3 and Ty3a confers a high level of resistance (DSI 0.2), and is not different than either of the resistant parents.

Conclusions: It should be recognized that not all of the comparisons contained all of the genotypes that would have been useful for making conclusions, that viruliferous whiteflies populations would have existed at different times, that several bipartite begomoviruses as well as Tomato yellow leaf curl virus would have been present, and that weather conditions may have impacted symptom expression. In general, the following observations were considered important concerning the various introgressions: 1) Ty3a was a more effective source of resistance than Ty4. 2) Ty2 either in the homozygous or heterozygous condition was not an effective source of resistance unless it was associated with another resistance gene, such as Ty3a. 3) The heterozygous families with Ty3a were not as resistant as families that were homozygous for this introgression (Fig. 6). 4) F1 hybrids with two different introgressions were highly resistant, such as Ty3a and Ty2 (Fig. 6) or Ty3a and Ty3 (Fig. 7). 5) There was considerable variation for the DSIs among the F3 families with same genotype for an introgression, which indicated that other genes were important in conditioning resistance. This was most notable in the F3 families from the cross of Gc143-2 by Gh188-2 (Fig. 5). Others have reported that several genes are involved in highest level of begomovirus resistance expression (Anbinder et al., 2009; Vidavsky and Czosnek, 1998; Zamir et al., 1994) and Anbinder et al. (2009) found that there were minor QTLs for resistance associated with both the resistant and susceptible parent used in the cross for their molecular analysis of resistance. 6) For the near future it is not enough to only use molecular markers for breeding for begomovirus resistance, but field evaluations with high levels of viruliferous whiteflies will continue to be an important part of any tomato breeding program for begomovirus resistance.

Research Papers TGC REPORT VOLUME 60, 2010 Preliminary report on association of ‘Candidatus Liberibacter solanacearum’ with field grown tomatoes in Guatemala

Luis Mejía, Amilcar Sánchez, and Luis Méndez, Facultad de Agronomía, Universidad de San Carlos de Guatemala; D. P. Maxwell, Department of Plant Pathology, University of Wisconsin-Madison; R. L. Gilberston, Department of Plant Pathology, University of California-Davis; V.V. Rivera and G.A. Secor, Department of Plant Pathology, North Dakota State University, Fargo. Introduction A new disease of tomatoes has received considerable attention in the local newspapers in Guatemala. Locally, it is referred to “Paratrioza disease”, which refers to the insect associated with symptomatic plants. The symptoms on tomatoes are flower abortion, purple margins of youngest leaves, upward cupping of leaves, thickened stems and retarded internode growth, and stunting of the plants (Fig. 1). In Mexico, a disease of tomato with similar symptoms is called permanent damage disease or permanent yellowing disease (daňo permanente del tomate; Páramo Menchaca, 2007) and Munyaneza et al. (2009) reported that Candidatus Liberibacter solanacearum was associated with these plants. This unculturable bacterium is transmitted by the tomato/potato psyllid (Bactericerca (Paratrioza) cockerelli).

Fig. 1. Typical symptoms associated with “Paratrioza disease” of tomato in Guatemala. Image taken December 2009 and shows flower abortion, purple leaf margins, cupping of leaves and thickened petioles and stems.

In a tomato field (about 0.7 ha, at 1,500 m, Department of Sacatepéquez) where symptom incidence was over 90%, samples of young leaves with typical symptoms were collected in December 2009. DNA was extracted at San Carlos University, Guatemala City (Garcia et al., 2007). PCR was performed at North Dakota State

55

University with 16s rRNA primers,CLi.po.F/O12c and PCR fragments sequenced using protocols reported by Secor et al. (2009). A PCR fragment of about 1,100 bp was obtained and sequenced in both directions. After correction by visual proofreading, a 966-nt region (contact D.P. Maxwell for sequence) was submitted to a BLAST analysis at the National Center for Biotechnology Information data base; and a 100% nucleotide identity was obtained with the 16s-23s rRNA intergenic spacer region for „Candidatus Liberibacter solanacearum’ from potato from Guatemala (FJ395205, Secor et al., 2009) and tomato from Sinaloa, Mexico (FJ957897, Munyaneza et al., 2009b). These sequences also had a 100% nucleotide identity with „Ca. L. solanacearum‟ from tomato in New Zealand (EU834130, Liefting et al., 2009a, 2009b), from bell pepper collected in Sinaloa, Mexico (FJ957896, Munyaneza et al., 2009a) and „Candidatus Liberibacter psyllaurous‟ (synonym „Ca. L. solanacearum‟, see discussion in Secor et al., 2009) from Zebra chip symptomatic potatoes in California (FJ498802, Crosslin and Bester, 2009). In Central America, Rehman et al. (2010) report the widespread occurrence of „Ca. L. solanacerum‟ (GQ926922) and its potato psyllid vector in potato fields in Honduras. Pair wise comparison of this sequence from „Ca. L. solanacearum‟ from potato with the Guatemalan „Ca. L. solanacearum’ sequence from tomato showed that there was a difference of two SNP between the sequences (678 nt), and this might indicate a different geographic origin of these two pathogens. Subsequently to samples collected in December 2009, samples were collected from tomatoes with either typical begomovirus symptoms and/or purple/yellowing symptoms on younger leaves in the Department of El Progresso in March 2010. The samples were prepared for transport to the University of California-Davis using AgDia absorption strips. This is a method to capture total nucleic acids from plant tissue in which sap is prepared from the target tissue, applied to an absorbent matrix on the end of a plastic 'stick', and allowed to dry prior to transport. DNA extracts were prepared from the 12 samples and tested for the presence of Liberobacter and begomovirus infection by PCR. 'Ca. Liberibacter sp.' was detected in 4 of 12 samples, and these samples showed symptoms of stunted and distorted growth; older leaves were yellow and brittle and younger leaves were upcurled with yellowing and vein purpling. Begomovirus infection was detected in all 12 samples. Additionally, 49 tomato samples were collected from March to June, 2010 and assayed for Liberibacter sp. using PCR primers CLi.po.F/O12c (Secor et al., 2009). The expected size fragment for Liberibacter sp. was obtained from 17 samples and no fragments were obtained with the other 32 samples. Positive PCR samples were collected from the following Departments: Sacatepéquez, Guatemala and Baja Verapaz,. These PCR fragments will be sequenced for more definitive identification. Universal PCR primers for phytoplasma (Smart et al., 1996) were used with the DNA samples from tomato collected in Guatemala and all were negative. Because of the purple top symptoms, phytoplasma were originally suspected as being present.

In the last two years, there has been considerable effort devoted to understanding the etiology of Zebra Chip (see Secor et al., 2009) and the new Candidatus Liberibacter sp. associated with solanaceous plants (see Liefting et al., 2009a, 2009b). These efforts plus the report here indicate that this unculturable bacterium transmitted by the tomato/potato psyllid will result in a serious disease for

56

tomatoes and peppers grown in the field or greenhouse (Brown et al., 2010) in Central America.

No universally accepted name exists for this disease on tomatoes, as illustrated by the use of different names: tomato vein-greening in Arizona (Brown et al., 2010), permanent yellowing in Mexico (Munyaneza et al., 2009b) and Paratrioza disease in Guatemala. At least from our observations in Guatemala several symptoms are notable: flower abortion, purpling of the leaf margins, stem thickening, yellowing of younger leaves, and stunting. An internet search reveals that there is a substantial number of sources using „permanente del tomate‟ or permanent yellowing disease of tomato. Thus, it is proposed that this diseased be named Liberibacter permanente del tomate or Liberibacter yellowing disease of tomato. This would distinguish this disease from psyllid yellows (Brown et al., 2010).

Research Papers TGC REPORT VOLUME 60, 2010 Study of epidermal cell size of petals and stamens in tomato species and hybrids using confocal laser-scanning microscopy Christopher Lofty, Julian Smith, Pravda Stoeva-Popova Department of Biology, Winthrop University, Rock Hill SC 29733 E-mail: [email protected] Introduction

The phenomenon of cytoplasmic male sterility (CMS) has been described and the genetics underlying the phenomemon studied in many species. Whether arising spontaneously, as the result of mutations, or through alloplasmic incompatibilities in interspecific crosses, the main effect of CMS is on the development of stamens and pollen, leading to aberrant stamens with no pollen or aborted pollen (Kaul 1988). Other changes correlated with the CMS phenotype are changes in the second whorl affecting petal size and color (Andersen 1963, 1964; Petrova et al. 1999; Farbos et al. 2001; Leino et al. 2003)

In the tomato, CMS does not occur naturally. CMS has been reported in interspecies hybrids. Andersen (1963, 1964) reported the emergence and increase of pollen abortion in F1 and backcrosses of the crosses between Solanum lycopersicum, S. cheesmaniiae (formerly L. chesmanii f. typicum and f. minor) or S. habrochaites (formerly L. hirsutum f. glabratum) used as pistillate parents and S. pennellii as the recurrent pollinating parent. Pleiotropic effects of the CMS phenotype included the reduction of anther length and size, and the lengthening of the filaments. The anther size was negatively correlated to the percent of aborted pollen.

Similar results were observed by Valkova-Atchkova (1980) in crosses involving S. peruvianum as pistillate parent and S. pennellii and S. habrochaites (formerly L. hirsutum f. typicum) as pollinating parents. Further introgression of the nuclear genome of the recurrent parents confirmed the stability of the CMS phenotype over many generations (Petrova et al. 1999, Stoeva et al. 2007).

As a preliminary step to dissecting morphological (and underlying genetic) changes occurring in the CMS phenotype, this study has focused on the comparative analysis of the size of epidermal cells from abaxial and adaxial sides of petals and stamens of mature flowers from CMS-pennellii line (0% stainable pollen), the isonuclear S. pennellii (100% pollen fertility), and the cultivated tomato S. lycopersicum. Materials and methods Plant material

In the study the following genotypes were used: Solanum lycopersicum (cv. Merkurii), Solanum pennellii (LA716), and CMS-pennellii (CMS line) previously described in Petrova et al. (1998) and Radkova (2002). To determine the size of the epidermal cells, fully expanded flowers in stage 20 according to the classification of Burkhin et al. (2003) were collected from plants grown in the same environmental

59

chamber with 24C/ 20C day/night temperature and 18/6 hours day/night photoperiod (Fig. 1). Tomato flower preparation for confocal microscopy: A 0.1% aqueous solution of calcofluor white (SIGMA) was made (Pringle 1991). Excess solution was kept in the freezer and defrosted as needed. Excised floral structures (petals, anthers or filaments) were immersed in approximately 5 ml of 0.1% calcofluor solution and placed under vacuum until rapid boil was achieved. The sunken specimens were allowed to soak for 20 minutes in the dark and then were rinsed in dH2O for 10 minutes. Specimens were dissected and placed on slides. For the anthers, spacers of approximately 0.5 mm – 1 mm thick were used to ensure the specimens were not smashed by the coverslip. Coverslips were placed on top and fixed with nail polish at each corner. Calcofluor staining of epidermal cell walls was observed using the DAPI channel of the confocal laser-scanning microscope (CLSM) (FV1000). Images were taken at the planes in which cell wall margins contacted each other. Cells were

counted in image frames measuring from 150 m X 150 m to 300 m X 270 m, with the frame size adjusted as needed to include from five to twenty cells in each frame.

Ten to fifteen cells from both sides (abaxial and adaxial) of each floral structure

were measured using ImageJ (Rasband, 2009) to obtain cell areas (in m2). The ANOVA and Tukey's LSD statistical tests (Minitab, Inc.) were performed separately for each epidermal floral surface across genotypes to determine if any significant difference existed between the mean surface areas of studied epidermal cells. Results Petal abaxial cell surface area was significantly different among the three genotypes (p < 0.001) with CMS line having the largest mean cell size and S. pennellii having the smallest (Figs. 2, 3). Petal adaxial cell sizes differed significantly with S. lycopersicum and S. pennelli both being larger than the CMS line (Fig 3). Although no statistical test was done, abaxial cells were smaller than the adaxial in the two species S. pennellii and S. lycopersicum. On the contrary, the abaxial cells in the CMS line were larger in comparison to the adaxial cells.

Epidermal cell area on both the adaxial and the abaxial surfaces of the anthers was significantly different (p< 0.001) among the three genotypes (Figs.4, 5), with S. lycopersicum having the largest mean cell size for both, and the CMS line, the smallest.

Among the filament epidermal cells, the abaxial cells in the CMS line and cultivated tomato were not significantly different, but both were significantly bigger than those in S. pennellii (p< 0.001) (Fig.6, 7). There were no significant differences in the mean size of the epidermal cells on the adaxial surface of the filaments of the three strains (p=0.252) (Fig.5, 6). There was a large variation (Fig. 7) in the size of the adaxial epidermal cells in S. pennellii and the CMS line, while the size of the adaxial cells of filament in the cultivated tomato showed less variation. Discussion

According to published data, cytoplasmic male sterility has a considerable effect on the size and color of petals and stamens (Kaul 1988, Farbos et al. 2001, Leino et al. 2003). Our previous studies had also shown that in comparison to S. pennellii, the CMS

60

flowers have smaller and lighter green petals and anthers and longer filaments (Fig 1; Petrova et al 1998). In addition to tomato nuclear male sterility mutants (reviewed in Gorman and McCormick 1997) ), similar changes of flower structures have been reported for tomato plants grown at low temperatures (Lozano et al. 1998) and in loss-of-function transgenic plants for the B-class genes required for petal and stamen identity (De Martino et al. 2006).

The size of plant organs is determined by cell division and cell expansion and elongation. Our investigation of the size of epidermal cells shows that the smaller size of the anthers in the CMS line (Fig. 1; Stoeva-Popova et al., unpublished) can be explained largely by the reduction in the size of the cells. The epidermal cells on both surfaces of the CMS anther were significantly smaller in comparison to S. pennellii: respectively 51% smaller on the adaxial side, and 42.3% on the abaxial surface. On the other hand, no corresponding effect of cytoplasmic male sterility on cell size in the petals was observed On the abaxial surface of the petals of CMS line, the cells were 81.5% larger than in S. pennellii, while on the adaxial side, they were 32.2 % smaller. According to our measurements (Stoeva et al., unpublished data) the CMS-pennellii filaments are several magnitudes longer than the filaments of S. pennellii (Fig. 1). This is not merely a consequence of increased cells size, as the filament epidermal cells of CMS are statistically larger than those of S. pennellii only on the abaxial side. CMS-pennellii and S. pennellii share the same nuclear genome and cytoplasmic male sterility affects expression of nuclear genes ( reviewed in Linke, Börner 2005, Chase 2006). Our results above show that cytoplasmic male sterility does not equally affect the development of petals, stamens and filaments.

Our study has shown that there are significant differences in the size of epidermal cells between the two species: the red-fruited cultivated tomato and the green-fruited S. pennellii. Significant differences were determined for the epidermal cells of the anthers and petals. The epidermal cells of the anthers of the cultivated tomato were larger, which is an indication that the anthers of S. pennellii have greater number of epidermal cells. The same conclusion could be drawn from the study of the abaxial epidermal cells of the petals and the filaments. Since the two species are not closely related it will be interesting to investigate other representatives of the tomato clade and to determine if the size of epidermal cells of flower structures can be indicative of species relatedness.

Although no statistical analysis was carried out, our data show one consistent feature across all genotypes: the largest epidermal cells were observed on anthers, while the ones with the smallest surface area were epidermal cells of petals.

TGC REPORT VOLUME 60, 2010 Revised List of Wild Species Stocks Chetelat, R. T. C.M. Rick Tomato Genetics Resource Center, Dept. of Plant Sciences, University of California, One Shields Ave., Davis, CA 95616 The following list of 1,196 accessions of wild tomatoes and allied Solanum species is a revision of the list published in TGC vol. 57, 2007. Other types of TGRC stocks are catalogued in TGC 58 (monogenic mutants) and TGC 59 (miscellaneous stocks). Inactive accessions have been dropped and new collections added to the present list. The new material includes populations of wild or feral cherry tomato (S. lycopersicum ‘cerasiforme‟) from Mexico (LA4352, LA4353), a stock of S. pimpinellifolium containing the sun gene introgressed from S. lycopersicum, and populations of S. peruvianum from the Azapa valley of northern Chile (LA4445-LA4448). Seed samples will be provided, upon request, for research, breeding or educational purposes. Some accessions may be temporarily unavailable for distribution during seed multiplication. In general, only small quantities of seed will be provided: 25 seed per accession for the self-pollinated accessions, 50 for the outcrossers or facultative accessions, and 5-10 for the allied Solanum species. These seed samples should be sufficient for researchers to produce larger quantities of seed, if needed. Accessions are grown for seed increase in the UC-Davis greenhouses, except for cherry tomatoes and certain populations of S. pimpinellifolium, which are grown in the field. The population sizes used for seed multiplication depend on the mating system, and are designed to maintain genetic diversity within accessions (see guidelines at http://tgrc.ucdavis.edu). The following tables are ordered by species name, using the classification system of Peralta et al. (2008)11, but with the equivalent Lycopersicon names listed as well. Although only brief collection site data can be presented here, more detailed records are available from our website, including geographic coordinates, images, and donor information. An appendix table lists the accessions belonging to the core subsets for each species.
