5. Breeder seed (Syn 1) was produced on cuttings of the parent clones near Nampa, Idaho with sufficient seed for the life of the variety held in controlled storage. Certified seed may be produced from either breeder or foundation seed. One generation each of breeder, foundation and certified seed is recognized. A maximum of three harvest years is permitted on stands producing foundation seed with five harvest years maximum on stands producing certified seed. Foundation seed production will be limited to the northern area of adaptation.
