Current through Register Vol. 46, No. 39, September 25, 2024
(a)
Limited generation.
All foundation seed shall be produced in a limited
generation production scheme. Seed lots are limited to a maximum of six
generations of propagation, designated as follows:
|
Class |
Generation |
| Foundation |
G1 |
| Foundation |
G2 |
| Foundation |
G3 |
| Foundation |
G4 |
| Foundation |
G5 |
| Foundation |
G6 |
Generation numbers increase with years of production from
the original seed source. Foundation class seed shall be downgraded
automatically one generation each year. The generation year for foundation
class seed shall be printed on tags by the certifying agency. When disease
tolerances for a seed class or generation are exceeded, seed lots shall be
lowered to the next acceptable seed classification or be rejected for
certification. The term Uihlein will be used to further
designate the first three generations of foundation seed originating from the
Uihlein Farm of Cornell University.
(b)
Foundation-Uihlein Generation
1.
(1) Seed obtained directly from the
Uihlein Farm of Cornell University will be eligible for planting.
(2) Grower shall enter entire potato acreage
for certification as foundation and/or certified seed.
(c)
Foundation-Uihlein Generation
2.
(1) Seed one year removed from the
Uihlein Farm of Cornell University and meeting the requirements of
Foundation-Uihlein Generation 1 will be eligible for planting.
(2) Grower shall enter entire potato acreage
for certification as foundation and/or certified seed.
(d)
Foundation-Uihlein Generation
3.
(1) Seed two years removed from the
Uihlein Farm of Cornell University and meeting the requirements of
Foundation-Uihlein Generation 1 will be eligible for planting.
(2) Grower shall enter entire potato acreage
for certification as foundation and/or certified seed.
(e)
Foundation-Generations 1 through
6.
(1) Seed originating from the
Uihlein Farm of Cornell University and meeting the requirements for foundation
or bearing foundation tags from New York, other states or Canada will be
eligible for planting.
(2) All
foundation seed lots originating from outside New York State must meet minimum
requirements of New York Blue Tag or New York Yellow Tag grades as confirmed by
State or Federal-State inspection certification.
(3) New York White Tag grade is not eligible
as planting stock for recertification unless it has been inspected by the
Federal-State Inspection Service.
(4) Potatoes planted by New York certified
seed growers utilizing planting stocks of their own production that are direct
progeny from eligible planting stocks and have passed a winter test acceptable
to the certifying agency.
(5)
Grower shall enter entire potato acreage for certification as foundation and/or
certified seed. Seed lots shall originate from in vitro culture in which all
plantlets have tested free from potato viruses A, M, S, X, Y (all may cause the
mosaic disease) and leafroll; potato spindle tuber viroid; Corynebacterium
sepedonicum (causes the ring rot disease); and Erwinia carotovora (causes the
soft rot and black leg diseases). Propagation of lots from the Uihlein Farm of
Cornell University or equivalent sources will be limited to six years with a
Generation 5 (G5) lot originating from outside New York State being the last
generation eligible for planting. A three-year exemption will be permitted at
the discretion of the certifying agency for numbered selections from breeding
programs or for named varieties for which pathogen-tested seed lots do not
exist or are not available.
