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.
