SUMMARY OF CERTIFICATION REQUIREMENTS
1. All potatoes planted within a farming operation must be approved for certification and entered for inspection.
2. All equipment and storage facilities within the farming operation must be used only for certified seed potatoes.
3. Each seed field must undergo at least two inspections during the growing season.
4. Storage facilities and equipment used for grading and handling seed potatoes must be cleaned, sanitized and inspected at
least once a year.
5. No bacterial ring rot may be found on the farming operation to qualify for Generation, Primary Foundation or Foundation
status.
6. The zero tolerance for bacterial ring rot means that no observed amount is allowed during inspection. The discovery of a
single plant in the field or a single tuber in storage infected with bacterial ring rot shall cause rejection of the field or lot.
The absence of a finding shall not be construed to mean that the field or lot inspected is free from the disease or disease
causing agent.
7. Certification requirements are not complete on any lot of seed potatoes until it has been properly graded, identified with
official tags or official bulk certificates, and has passed official grade inspection.
8. Final grading inspection and tagging is under the supervision of Federal-State inspectors and a certificate of inspection
must accompany each shipment.
WINTER TEST
In order to help determine if any late season spread of certain virus diseases has occurred, all fields of Generation, Primary
Foundation and Foundation class seed are sampled at harvest for additional testing during the winter. Minnesota's winter test
standards require that there be no more than one half of one percent of any or all virus diseases, and no spindle tuber or
chemical damage detected in the sample.
LIMITED GENERATION CERTIFIED SEEDS
Limited Generation certified seed potatoes must originate from pathogen tested in vitro plantlets and may be replanted for
certification only a limited number of years. The classification of a Limited Generation seed lot changes each year that it is in
the field, going sequentially from Nuclear to Generation 1 through Generation 5.

CONVENTIONAL CERTIFIED SEED
Conventional certified seed potatoes are initiated by clonal selection and the tuber unit technique on a primary foundation seed
farm. Seed produced from a tuber unit plot is classified as Primary Foundation 1. The following year, Primary Foundation 1
seed is planted to produce Primary Foundation 2 seed. The seed then leaves the primary foundation farm and goes to a
foundation seed farm where it is increased as Foundation class seed. Seed lots not meeting Primary Foundation or
Foundation requirements are classified as Certified.

GRADE REQUIREMENTS
The BLUE tag is issued on lots that have met all field and storage inspection requirements as well as standards higher
than the U.S. No. 1 Seed Grade for size, condition and physical defects.
The YELLOW tag is issued on lots that have met the same certification requirements as blue tag, however, there is a
higher grade tolerance for certain physical defects and mechanical injury.
The WHITE tag is issued on lots meeting the same certification requirements as yellow tag, except that grade is according
to agreement between buyer and seller as to size and certain defects. The white tag is for intrastate use only.
SEED LOT CLASSIFICATION
Seed lot classifications shown in this directory are based only on field inspection results. Final classification is contingent upon
a tuber sample being submitted and passing the winter test.
KEY TO ABBREVIATION AND TERMS
Lot = A field designation assigned by the grower for identification and record keeping purposes.
* = Indicates a field was tested for Potato Virus X and showed no more than 3% infection.
PN = Pre-Nuclear PF1 = Primary Foundation 1
N = Nuclear PF2 = Primary Foundation 2
G1 = Generation 1 F1 = Foundation 1
G2 = Generation 2 F2 = Foundation 2
G3 = Generation 3 C = Certified
G4 = Generation 4 CPB = Colorado Potato Beetle
G5 = Generation 5 PLRV = Potato Leafroll Virus
FG = Field Generation PVY = Potato Virus Y
FY = Years in Field
A variety may be protected by the Plant Variety Protection (PVP) Act. Buyers should validate the status
of the variety from the vendors and variety owner.
DISCLAIMER
A certification does not represent a warranty of any kind, expressed or implied, including merchantability, as to the quality of
the crop produced from the certified seed potatoes. A certification represents only that the seed potatoes were produced,
graded, sacked or placed in bulk, and inspected in accordance with Minnesota Rules Parts 1555.6720 to 1555.6950.

NOTICE
Line Selections / Varietal Strains
The Minnesota Department of Agriculture Seed Potato Program certification confirms that each lot of potatoes in this directory
have met the standards or requirements of State law, including but not limited to variety name and presence or absence of
disease. This directory may also include line selection/varietal strains of certain identifiable varieties. This is indicated as
“source documented as”. Although the certification tag may designate variety, strain or line selection names, that information
is derived solely from the documentation supplied by the applicant for certification. Individual seed growers may have
developed, or obtained from another source, lines/strains that possess yield, maturity, vine or tuber characteristics that may be
different from the variety as originally described and named. A line/strain cannot usually be distinguished from the parent
potato variety by conventional certification methods or by laboratory testing means. The seed grower is responsible for
informing the seed buyer about line/strain existence and characteristics. Seed buyers should ask seed sellers about
lines/strains that may be included among the seed lots listed.

1
The purpose of this table is to express equivalency of terms used by various certification agencies for seed potatoes harvested from a
series of successive field plantings. For specific criteria relating to disease tolerances and other requirements, the reader is referred to the
certification regulations of the agency in question.
2
The first field planting utilizes laboratory-tested stocks which may be tissue-cultured plantlets, greenhouse-produced minitubers, stem
cuttings, or line selections. Contact agencies for details as to types of stocks planted in their programs.
3
Term used by agency for seed potatoes for a particular year in the field: C=certified, E=elite, F=foundation, G=generation, N=nuclear,
PE=pre-elite.
4
If lots originate at Cornell-Uihlein Farm, the first three generations (G1-G3) are also designated by a “AU@” to denote source.
5
Lots NOT originating at the UW Lelah Starks Elite Foundation Seed Potato Farm are designated Gn where n = years in the field.
6
FY= Field Year
