Cherry production in Croatia:5.000 - 8.000 tona [2006.-2010.]
� Production of sweet cherry in Croatia has been without high economic significance for many years, in spite of high prices(even 20 Eur/kg) (Vjesnik, 6.5.2005.).
� Production is fragmented on small plots and gardens
� Recently, there is grow in interest for sweet cherry production due to availability of contemporary self-compatible varieties, technologies and rootstocks.
150 kn = approx. 20 EURfor South-African sweet cherries in a retail shop
Recent literature states seven varieties as ‘’native varieties’’
Their production is concentrated in several production areas:
Liburnia (north Adriatic): 'Lovranska', 'Creska'Dalmatia (south Adriatic): 'Stonska', 'Tugarka', 'Gomilička'Pannonia (continental. pt.): 'Okićka', 'Kutjevačka‘
'Creska'
'Lovranska'
‘Okićka'
‘Kutjevačka'
‘Gomilička'
‘Stonska'
‘Tugarka'
The goal of this presentation is to give:
� an overview of native sweet cherry varieties in Croatia
� a history of varieties grown in Croatia
� a hypothesis on the possible identity of these varieties
� direction for further research [molecular / morphological]
Starting points about native varieties:
� All varieties have names according to toponyms: geographical names of villages, towns or mountains.
� Their origin is not known
� Their overall identity is a kind of mistery
� Their S-allele constitution is not known
� There is probability of synonymity
� The common characteristic for these varieties: heart-like fruit shape, firm flesh texture, medium to late ripening, transportability, long storage, high weight of the fruits (9-10 g. in extensive production).
� Rich aroma, high sugar content, excellent balance between sugar / acids.
= Similar fruit morphologycv. ‘Creska’ (north Adriatic)
cv. ‘Kutjevačka’ (continental part) cv. ‘Tugarka’ (south Adriatic)
‘Lovranska’� Medium vigor in Gisela-6
� Fruits are of medium weight, firm texture, god transportability, medium to late ripening, pleasant aroma.
cv. ‘Lovranska’ (north Adriatic)
cv. ‘Stonska’ (south Adriatic)
‘Stonska’� Fruit is big, rounded to heart-shaped, very firm
texture, good transportability, stem is very long.
� Low acidity, high content of sugar.
� Ripening: in between ‘Gomiličke’ and ‘Tugarke’.
‘Gomilička’� Very early ripening (beginning of May)
� Very juicy, soft flesh, the weight of fruit ismedium, very sweet
� Susceptible to transportation
‘Okićka’� Very late-ripening variety
� Fruit is very firm with good transportability,rounded.
� Weight of fruit is small to medium.
� Very sweet, has good and pleasant aroma.
cv. ‘Gomilička’ (south Adriatic)
cv. ‘Okićka’ (continental pt.)
The drawbacks:
� Measurements only in situ: there is no colection orchard
� Varying conditions in orchards: different rootstocks, technology, climate, soil
� Limited availability of the full range of reliabletrue-to-type plant material for DNA analyses
cv. ‘Okićka’ (continental pt.) cv. ‘Creska’ (north Adriatic)
But let’s go back to the names of ‘native’varieties:
� They are all named after certain geographical toponym from the area where grown
� The names of ‘Tugarka’, ‘Creska’, ‘Lovranska’ etc. does not exist in old books
K.J. Veselić:Fruit growing,
1848.Does not mention any sweet cherry variety, but classify them according to early-ripening, late-ripening, firm-texture etc.
Antun Trumer:Fruit growing,
1881.Frühe Maiherzkirsche, Büttners
schwarze Herzkirsche, Fromm’s, Krügers, Winklers, Tilgeners,
Elton, Adams, Jahns Durchsichtige, Flamentiner, etc.
Few of these varieties are stated in Tobutt et al. (2004.)
Fran Kuralt:Fruit growing for people,
1884.Frühe Maiherzkirsche, Büttnersschwarze Herzkirsche, Fromm’s, Krügers, Winklers, Tilgeners, Elton, Adams, Jahns Durchsichtige, Flamentiner, etc.
Fran Kuralt: Fruit growing,
1889.Frühe Maiherzkirsche, Büttners schwarze Herzkirsche, Fromm’s schwarze Herzkirsche, Krügers, Winklers schwarze Knorpelkirsche, Tilgeners rothe Herzkirsche, Elton, Adams Herzkirsche, Jahns Durchsichtige, Flementiner, etc.
Fran Kuralt: Fruit growing,
1889.Same varieties like the issue of 1889.
Ivan pl. Radić: Fruit growing,
1909.Hedelfingen, Adler’s schwarze
Herzkirsche, Elton’s Herzkirsche, Esperens, other varieties in type of Knorpelkirsche and Herzkirsche, etc.
Stanko Ožanić et al: Fruit growing,
1903.Hedelfingen, Hortensia, Elton’s
Where are the names of native varietiesin old literature!?
Agricultural lexicon
1985.Tugarka, Stonska, Gomilička,Vipavka, Ohridska
I. Miljković: Contemporary Fruit Growing
1991.Tugarka, Ohridska, Vipavka, Gomilička
M. Radunić et al.: Cherries
2007.Tugarka, Stonska, Gomilička
Where are the names of ‘old’ varietiesin recent literature!?
In the same time, recent literature does not mention any of the ‘old’ varieties listed in the ‘old’ literature.
Where is the ‘continuity of variety names’ being lost!?
Probably some of ‘native’ varieties are, in fact,
synonyms of the old varieties as a consequence
of unofficial introduction in recent history (100 – 150 years ago)!?
Maybe some of ‘native’ varieties are synonyms among themselves!?
A drawback of traditional propagation: the loss of genuine variety name due to
traditional way of propagation without official control (certifications).
The varieties got its name after the geographic place (toponym) from where the spreading (propagation) was most intensive.
SSR analyses:� Traditional polyacrylamide method
� Genetic analyzer ABI 3130
Synonymity detected:� Some of ‘native’ varieties are synonyms in 10 SSR loci: � Some of Croatian ‘native’ varieties are synonyms to some of
‘native’ varieties from the region (Slovenia to Macedonia)
Synonymity confirmed:� Those ‘native’ varieties that are synonyms in 10 SSRs have also
the same S-allele constitution
Synonyms are: four varieties[they also have similar morphology], but also few other local varieties (genotypes) from ex.Yugoslavia (not stated below).

Conclusions and future work:
� Looking for synonyms can be reduced within the group of the varieties with the same S-allele constitution [ref. Tobutt et al. (2004.), Iezzoni et al. (2005.)
� establishment of European collaborative network with standardized protocols and refferal allele sizes (samples) [there were attempts to this goal: Clarke & Tobutt, 2007.]
� establishing the database similar to those in Vitis research group [Maul et al., 2012.]
