2017 CERTIFIED SEED POTATO DIRECTORY

Listed are those growers with potatoes produced for the 2017 crop qualifying for certified seed. Included in the directory

are acreage of cultivars approved following field inspections (storage inspections will be completed after harvest), lot

identification, generation, and final inspection field readings. Cultivars with acreage less than 0.10 total or private cultivar

upon owners’ request are not listed. Feel free to inquire from any grower listed about additional information you believe

may be of assistance in evaluating their seed lots. The seed grower can verify that any given seed lot you may wish to

purchase has been stored separately. It sometimes becomes necessary for seed growers to store similar seed lots of the same

cultivar in a single bin which could result in loss of the individual lot identity listed herein.

IN ADDITION, ALL SEED GENERATIONS IN THE DIRECTORY ARE BASED ON FIELD INSPECTION

READINGS. THESE CLASSIFICATIONS COULD CHANGE BECAUSE OF RESULTS OBTAINED DURING

STORAGE, SHIPPING POINT INSPECTION, POST HARVEST TESTING, ETC. IT IS THE BUYER’S

RESPONSIBILITY TO VERIFY SEED LOT GENERATIONS WITH THE SEED GROWER.

RE-CERTIFICATION CONDITIONS

Not all certified seed will be eligible for re-certification. ONLY THOSE LOTS MEETING POST HARVEST TEST

REQUIREMENTS OR OTHER STANDARDS WILL BE APPROVED FOR RE-CERTIFICATION. A

supplementary list will be available following completion of post harvest testing to identify eligible lots.

EXCEPTION

Any lot(s) of seed proven to be infected with bacterial ring rot or otherwise unfit for seed will be rejected for

certification regardless of the time or place of inspection.

Certain Colorado regulations may additionally limit the eligibility of seed lots for re-certification. Please note the following

explanation which identifies seed lots that are affected by these regulations.

Preceding each grower’s name in the Directory is a space which may be blank or have an asterisk (*). The same symbol is

located immediately preceding lot identity in the main body of the Directory.

Blank - The grower’s lots listed passed all field inspection requirements and are approved as certified seed. All lots are

eligible for re-certification contingent upon required storage inspection, post harvest test results, and generation.

* - The grower’s lots listed passed all field inspection requirements and are approved as certified seed; however, this

grower had a lot(s) of seed potatoes in his farming operation rejected due to bacterial ring rot. Any seed lot with an

* in its designation shall not be eligible for re-certification the following year except by the original grower or the

farming operation where bacterial ring rot was identified. The * symbol will also be printed on all of the grower’s

tags and bulk certificates.

PLEASE KEEP THESE DESIGNATIONS IN MIND WHEN UTILIZING THIS DIRECTORY.

BLACKLEG FIELD READINGS

Blackleg field readings are included in the Colorado Seed Directory in response to numerous requests from seed buyers.

Although estimates of blackleg percentages are routinely collected by field inspectors, this data is not necessarily a reliable

indicator of blackleg in the crop grown from any given seed lot. Environmental conditions and cultivar response to infection

can either magnify or suppress blackleg symptom expression sufficiently to prevent a reasonable correlation between the

seed source reading and the next crop grown. These field readings, however, may be a useful indicator of blackleg reinfection

into seed lots originating from laboratory produced, tissue-culture propagated stocks.

LINE SELECTIONS

The Potato Certification Service verifies that each cultivar listed in this Directory has been correctly identified. Some

individual seed growers, however, may have developed or obtained from another source, line selections that possess

characteristics such as yield potential, maturity, vine and/or tuber type that could be different from any given cultivar as

originally described and named. Since such characteristics cannot usually be verified on a reliable basis by conventional

certification methods, the responsibility for informing the seed buyer about line selection characteristics rests with the seed

grower. Therefore, seed purchasers are urged to consult with the seed grower about line selections that may be included (but

not identified) among the seed lots listed.

DECIMAL PERCENTAGES USED IN REPORTING FIELD READINGS

The field reading percentages used in this Directory are calculated from actual plant counts made visually by inspectors when

they walk through the fields. The number of diseased, or otherwise undesirable plants accumulated in any given inspection

are divided by the total number of plants observed. The numerical result is a decimal percentage. To help you visualize

decimal percentages to actual frequency of diseased plants in a field, it is helpful to express it in terms of diseased plants per

10,000. The table below illustrates how decimal percentages relate to plants per 10,000.

Field Reading Percent Diseased Plants per 10,000

0.01 1

0.05 5

0.10 10

0.20 20

Etc.

EXPLANATION OF GENERATION SYMBOLS

Generation Lab and/or Greenhouse Production

Nuclear Lab tested; tissue-culture or stem-cut propagations; plantlets,

microtubers, or greenhouse produced minitubers.

Field Production

1 (G1) First year of field production (planting from nuclear stocks)

2 (G2) Second year (G1 planting)

3 (G3) Third year (G2 planting)

4 (G4) Fourth year (G3 planting)

5 (G5) Fifth year (G4 planting)

6 (G6) Last year of field production (G5 planting). G6 stocks cannot be re-

entered for certification.

Non-Generation Certified (NGC) Planted from certified stocks of cultivars for which tissue-culture

derived, lab tested seed sources are temporarily not available. NGC

stocks must meet qualifications for re-certification and are inspected

and classified according to the disease tolerances and all applicable

rules and regulations established for G6.

Experimental (EXP) Includes unnamed “seedling” clones (Please see Special Requirements

for Experimental Class Seed Potatoes in the appendix of this

Directory).

EXPLANATION OF LOT NUMBER DESIGNATIONS

Each lot number consists of several parts. For example, the following lot number “17020ATL41" consists of...

17 = 2017: the year of production

020 = Scidmore Farms: the grower’s individual ID number

ATL = Atlantic: the cultivar designation

4 = generation 4: the generation of the seed lot (see above)

1 = the first lot of generation 4 Atlantic seed on grower ID 020: The number of individual lots of that

particular cultivar by generation. There may be more than one lot of a particular cultivar by generation.

Numbers would progress; 2, 3, 4, etc. based upon the actual number of similar lots on the grower’s farm.

We hope this explanation will clarify how each lot number is derived.

APPENDIX

TAGS, BULK CERTIFICATES, SEALS

a. No potatoes are recognized as officially certified unless properly tagged or identified with a bulk certificate.

Illegal use of tags or bulk certificates will be prosecuted.

b. Tags or bulk certificates will be issued only to the applicant or his agent. NO MUTILATION OF TAGS OR

BULK CERTIFICATES, BY WRITING OR MARKING OVER, OR OTHERWISE ALTERING

ORIGINAL INFORMATION PRINTED THEREON, WILL BE PERMITTED. The responsibility of proper

use of tags and bulk certificates are placed on the person (CCPGA member) to whom such articles have been

issued.

c. A metal seal shall be placed on the conveyance doors of bulk shipment containers identified by a bulk certificate.

d. Special permission may be granted by the CCPGA Board of Directors to imprint a duplicate image of an official

Colorado Certified Tag on a small plastic bag (3 lbs. to 10 lbs.) to be used for marketing small quantities of

certified seed potatoes. The art work layout must be approved by the Potato Certification Service prior to

printing. Information normally printed on the Colorado seed tag (i.e., seed grower's name, cultivar, crop year, lot

number, and maximum tuber size) will be printed on the bag in order that the reader can readily identify the seed

source. One completed copy of a bag bearing all of the above mentioned information related to a given shipment

must be filed with the Potato Certification Service. All such shipments must comply with designated grade

inspection requirements. A bulk certificate will accompany each load.

GRADES AND GRADE INSPECTION

a. All Certified Seed Potatoes must be graded to conform with the Colorado standard grades and sizes for seed

potatoes unless a signed waiver of grade inspection has been obtained from the purchaser as outlined in Section

14-d or an exemption has been obtained from the CO PCS as outlined in Section 14-h.

b. All seed potatoes must be shipped under tags or bulk certificates that represent the grade to which they have been

sorted. Potatoes failing to meet the grade specified on the tag or bulk certificate will be; (1) resorted to meet the

grade requirements, (2) re-tagged with new tags or re-issued a new bulk certificate representative of the grade of

the potatoes, or (3) the tags must be removed.

c. All shipments must be inspected by a Federal/State Inspector at the time of shipment. The Federal/State

Inspection Service is responsible for inspecting seed shipments to verify that proper grade standards have been

met. If a "zero tolerance" disease such as bacterial ring rot or root knot nematode is suspected or any other

condition which may disqualify a seed lot from certification is discovered during the inspection, the Potato

Certification Service will be notified by the seed grower and suspect tubers submitted to the Potato Certification

Service so additional procedures can be implemented to identify and confirm the true nature of the problem.

Upon confirmation of a “zero tolerance” disease or pest, the remaining portion of the affected lot will be rejected

from certification and it will be the responsibility of the seed grower to notify all recipients of the previous shipments

of the lot of the finding of a “zero tolerance” disease or pest.

d. Seed cut prior to shipment must be accompanied by a signed cut seed disclaimer and waiver, and an official tag or

bulk certificate indicating that the seed potatoes are “CUT SEED.”

e. Each lot sold within a Marketing Order Area shall be inspected by a Federal/State Inspector.

f. All Certified Seed Potatoes marketed in bags and carrying a tag must meet the highest grade requirements

indicated by either the bag or the colored tag. U.S. No. 1 Seed Grade is not strictly a U.S. No. 1 grade, and may

not be marketed in bags branded as U.S. No. 1.

g. All Certified Seed Potatoes exported outside of the U.S. shall meet the U.S. EXPORT "SEED POTATOES"

standards for the given class being shipped.

h. Certified Seed Potatoes marketed expressly for use as garden seed and shipped in quantities less than 24 cwt per

cultivar or clone within the same load shall be exempt from Federal/State grade inspection. However, an

‘inspection exemption for certified seed potatoes’ shall be obtained from the CO PCS verifying the load as containing

less than 24 cwt per cultivar, and a waiver of grade inspection must be secured from the purchaser at the time of

delivery or acceptance.

Colorado Blue Tag Grade shall consist of potatoes which meet the requirements of the disease tolerances and grade

standards previously listed for CERTIFIED SEED POTATOES. In addition, they shall be graded to conform with the

U.S. No. 1 Seed Potatoes Grade as defined under U.S. Standards for Grades of Seed Potatoes with the following

exceptions:

1. Not more than 1% of the potatoes shall be damaged by dry rot.

2. Size shall be 1-1/2" to 12 oz.,size is not required on the tag, a smaller maximum however, will be

specified on the tag or bulk certificate. 3. Not more than 3% of the potatoes in any lot may be below the specified size and, in addition, not more

than 8% may be above the specified size.

4. Physiological internal pigmentation shall not be considered a grade factor.

Colorado Yellow Tag Grade shall consist of potatoes which meet the requirements of the disease tolerances and grade

standards previously listed for CERTIFIED SEED POTATOES. This grade is intended to provide the buyer and seller an

opportunity to establish certain mutually agreed upon specifications not allowed in the Colorado Blue Tag Grade. The

potatoes must be graded to conform with the U.S. No. 1 Seed Potatoes Grade as defined under U.S. Standards for Grades

of Seed Potatoes with the following exceptions:

1. Soft rot shall not exceed 1%.

2. Tuber size shall be specified on the tag or bulk certificate. Tolerances for specified size limits: Not more

than 3% of the potatoes in any lot may be below the stated minimum and, in addition, not more than 10%

may be above the stated maximum.

3. Tubers shall not be seriously damaged by external defects, or seriously misshapen unless otherwise

specified, and shall meet the tolerances for a U.S. No. 1 Seed Potato Grade.

4. Physiological internal pigmentation shall not be considered a grade factor.

5. There will be no requirements for sprouts.

Applications of Tolerances: The application of grade and size tolerances shall be as outlined in the United States Standards

for Potatoes, Section 51.3003.

U.S. Export "Seed Potatoes" shall consist of potatoes which meet the requirements, disease tolerances and grade

standards for international export as listed under the U.S. EXPORT STANDARDS FOR SEED POTATOES; Appendix

P, USDA Export Certification Manual; 3/99.

SPECIAL REQUIREMENTS FOR EXPERIMENTAL CLASS SEED POTATOES

The Memorandum of Understanding between the Colorado Certified Potato Growers’ Association and the Board of

Governors of the CSU System authorizes the Potato Certification Service to "cooperate with the Experiment Station in

increasing and releasing new varieties of potatoes developed by the Experiment Station," thus it becomes necessary to

develop acceptable guidelines for conducting the testing and seed increase program. In this respect, it is important to

acknowledge the unavoidable limitations to the visual inspection process encountered when the disease symptom

expression of any potato clone is unknown at the time a seed grower would like to enter it for certification. Therefore, the

Experimental Seed Category was established to expedite and facilitate field testing of numbered potato clones being

considered for naming and official release. Two categories of this Seed Class were established.

Category 1 will include only unnamed "Seedling" potato clones involved in the field testing phase of a potato cultivar

development program on which bacterial ring rot and/or leafroll virus symptom expression is unknown. Seed stocks of

such clones will not be eligible for certified tags or bulk certificates, nor will they be listed in the Seed Directory. Field

plantings of such clones will be inspected and a written report submitted to the Leader of the Cultivar Development

Program. When adequate field test data on disease expression and other performance characteristics has been collected to

justify further evaluation on seed growers farms, any given clone may be transferred to Category 2 of the Experimental

Seed category. This decision will be made jointly by the Leader of the Cultivar Development Program, the Potato

Certification Service and the Seed Improvement Committee of the Colorado Certified Potato Growers' Association.

Category 2 seed lots will include only unnamed "Seedling" clones whose symptom expression of bacterial ring rot and

potato leafroll virus are known to be adequate under Colorado field conditions. Such seed lots will be eligible for entry

into the certification program on the following basis: There will be three years production allowed for Experimental Seed -

Non-Generation Category 2 stocks. At the end of three years, the status of these stocks will be reviewed and, where

possible, these stocks will be phased out and replaced with Limited Generation seed sources. If this is not possible, an

annual review will be conducted to verify the status of the stocks. This decision will be made jointly by the Leader of the

Cultivar Development Program, the Potato Certification Service and the Seed Improvement Committee of the Colorado

Certified Potato Growers’ Association. Non-Generation Category 2 seed lots will be inspected and classified according to

the disease tolerances and all of the applicable Rules and Regulations established for Generation 6. All stocks which meet

the criteria for certification will be listed in the Seed Directory. The symbols "Exp 2-" followed by a number designating

the years in the field after initial release (i.e., Exp 2-1, Exp 2-2, etc.) will be printed both in the Seed Directory and on tags

and bulk certificates. Limited Generation sources of these stocks will carry the same designations with the exception that

the symbols after "Exp 2-" will reflect their status from the Limited Generation program, (i.e., Exp 2-G1, Exp 2-G2, etc.).

Because of the limited knowledge concerning potential disease reactions, and/or other problems in these seed stocks, the

seed seller must obtain and submit to the Potato Certification Service an affidavit signed by the seed buyer prior to seed

shipment which states that the buyer is willing to accept the risks involved with purchasing experimental seed. This

affidavit or its equivalent will be kept with the tag or bulk certificate order in the grower's Potato Certification Service file.

Also, it is understood that experimental seed stocks may be rejected at any time due to uncommon disease reactions.

Any seed grower/organization entering numbered potato selections for seed increase and evaluation in the potato certification

program also agrees to abide by an agreement with the Colorado State University Agricultural Experiment Station, or to

obtain written authorization from the potato breeding program from which the numbered potato selections originate. The

CSU agreement “Notice to Receivers of Experimental Potato Selections” consists in part of the following:

COLORADO STATE UNIVERSITY AGREES TO:

1. Supply seed stocks or grant permission to utilize these stocks for further propagation and evaluation to the grower

applicant.

2. The term of this agreement will be for a one year period beginning upon seed grower/organization receipt of the

numbered stocks.

BY ACCEPTANCE OF SUCH POTATOES, THE SEED GROWER/ORGANIZATION AGREES TO:

1. Enter crop for certification. These stocks will be grown in accordance with the Rules and Regulations of the seed

potato certification program for the appropriate seed class using generally accepted cultural practices.

2. Furnish land and labor, and meet all expenses involved in production and certification of the crop.

3. Permit representatives of the University to make observations and to obtain samples if desired. 4. Not to further propagate or distribute seed stocks of this (these) selections for propagation beyond the terms of this

agreement unless authorized by the University.

5. Dispose of any numbered selection discarded from the Potato Cultivar Development Program. These stocks will

not be eligible for entrance in any seed potato certification program unless authorized by the University.

6. Special disposition instructions: As directed by Cultivar Development Program Leader.

7. A meeting between the Seed Grower(s)/Organization Representative(s), the Seed Improvement Committee of the

Colorado Certified Potato Growers' Association, the Potato Certification Service and the Project Leader of the

Potato Cultivar Development Program prior to January 1st to establish guidelines on price and method of

distribution of seed.

8. Not hold the University or its representatives financially liable for losses incurred as a result of production and/or

disposition of this seed.

IT IS MUTUALLY AGREED:

1. The proceeds from the crop produced under this agreement shall be the property of the Seed Grower/Organization

that submitted the stocks for certification.

2. That information derived from these evaluations shall be jointly shared by the parties to this agreement.

3. That the selections may be legally protected under the federal Plant Variety Protection Act or other mechanisms

that may require royalty payments before being grown commercially.
