5. Seed increase is on a limited generation basis with one generation each of breeder and certified seed classes, and two generations of foundation seed. Breeder (Syn. 1), foundatIon (Syn. 2 or Syn. 3), and certified (Syn. 3 orSyn. 4) classes will be recognized. Production of Syn 3 foundation seed requires the consent of the breeder. Breeder seed was produced under cage isolation at Woodland, CA. Sufficient foundation seed for the projected life of the variety will be maintained by Cal/West Seeds.
