5. Seed increase of WestStar is on a limited generation basis with two generations of the breeder, foundation, and certified seed classes. Breeder (Syn. 1 or Syn. 2), foundation (Syn. 2 or Syn. 3), and certified (Syn. 3 or Syn. 4) classes will be recognized. Production of Syn. 2 breeder or Syn 3 foundation seed requires the consent of the breeder. Breeder seed was produced under open isolation at Hollister, California in 1991. Sufficient foundation seed for the projected life of the variety will be maintained by Cal/West Seeds. Stands of foundation and certified seed fields are limited to 3 and 6 years, respectively.

6. Certified Seed of WestStar will be available in 1996.
