 New rice varieties developed through the breeding program at the Rice Experiment Station are recommended for release by the Board of Directors of the California Cooperative Rice Research Foundation. This recommendation is reviewed by a committee in the UC Department of Agronomy and Range Science and, if acceptable, is approved for release. This committee also recommends new varieties for certification. The Board of Directors of the California Crop Improvement Association approves certification.

The first increase of breeders seed, called foundation seed, is done at the Rice Experiment Station. Foundation seed production is financed by selling the seed to seed growers. The seed growers produce registered seed from the foundation seed and certified seed from registered seed. Production of foundation, registered and certified seed is supervised and controlled by the California Crop Improvement Association.

An estimated 90 percent of California's rice crop is planted from these three classes of seed (Fig. 3). Calmochi 101 and M-202 are new varieties coming into the program. M-7 and M-101 are varieties being discontinued and replaced by newer ones. Adequate certified seed is available for planting the 1986 rice crop.

This system has prevented red rice from becoming a problem in California.
