Foundation seed will be produced from Breeder seed and Certified seed either from Breeder or Foundation seed. One generation each of Breeder, Foundation and Certified seed class is recognized. A maximum of three years each is permitted on stands producing Breeder and Foundation seed with five years of Certified seed. 6. Certified seed will be available spring of 1987. 7.
