1. C/W-62 (experimental designation) is a synthetic variety with 168 parent plants. Parents were selected from USDA germplasm releases Beltsville 2-An4 (48), Beltsville 3-An4 (48), and the variety 131 (44) which were screened for resistance to Phytophthora root rot and anthracnose. Additional parent plants trace to spotted alfalfa aphid resistant selections from the USDA germplasm release MSB-CW5 (28). These plants were intercrossed under cage isolation at Woodland, California to produce Syn 1 seed.
2. C/W-62 is a hay and haylage type variety adapted to the northern and central Midwestern U.S. It has been tested in South Dakota, Minnesota, Wisconsin, Illinois, Michigan, Pennsylvania, New York, Nebraska, N. California and Ontario, Canada.
3. Fall dormancy is approximately equal to Saranac. Flower color is approximately 90% purple and 10% variegated.
4. C/W-62 has resistance to bacterial wilt, Fusarium wilt, Phytophthora root rot, Race I anthracnose and pea aphids. It has moderate resistance to the spotted alfalfa aphid and Race II anthracnose. Reaction to stem nematode has not been determined.
5. Breeders (Syn 2) seed was produced in field isolation at Helm, California in 1977. Seed increase is on the limited generation basis with one generation each of Breeder, Foundation and Certified seed classes. Breeders (Syn 2), Foundation (Syn 3), and Certified (Syn 3 or Syn 4) with limitations on age of stand 1, 3, and 6 years respectively, will be recognized. Sufficient Foundation seed of this variety for its projected life will be maintained in environmentally controlled storage by Cal/West Seeds.
6. Certified seed will be marketed in the fall of 1981.
7. Application for Plant Variety Protection is not contemplated.
