82 Ca B

1.   82 Ca B is a synthetic variety composed of 264 clones selected for resistance to Phytophthora root rot from two experimental lines that exhibited excellent persistence and yield potential in forage yield tests at Bakersfield, CA. Source material had been screened previously for resistance to one or more of the following: spotted alfalfa aphid, pea aphid, blue alfalfa aphid, Fusarium wilt and bacterial wilt. Germplasm sources trace primarily to Sonora, Moapa, Kansas common, Lahontan, and Buffalo, with limited contributions from Saranac, Ranger, and Atlantic. Approximate germplasm source contributions are: Ladak - 3%, M. varia - 14%, Turkistan - 25%, Flemish - 12%, Chilean - 15%, Peruvian - 1%, Indian - 1%, and African - 29%.

2.   82 Ca B is a non-dormant variety adapted for use in the southwestern U.S. for hay, haylage, and dehydration purposes. 82 Ca B has been tested for forage yield in California and Arizona.

3.   Fall dormancy is similar to Moapa 69. Flower color is 99% purple and 1% variegated. Midsummer and fall growth is erect.

4.   82 Ca B has high resistance to pea aphid, spotted alfalfa aphid, blue alfalfa aphid, Phytophthora root rot and Fusarium wilt; resistance to stem nematode; and moderate resistance to bacterial wilt. Its reaction to Verticillium wilt and anthracnose has not been evaluated.

5.   Seed increase is on a limited generation basis with one generation of breeder and two generations each of foundation and certified seed classes. Breeder (Syn. 1), foundation (Syn. 2 or Syn. 3) and certified (Syn. 3 or Syn. 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 Bakersfield, CA. Sufficient foundation seed for the projected life of the variety will be maintained by W-L Research.

6.   Certified seed will be marketed in 1990.

7.   No decision has been made concerning Plant Variety Protection.
