CW3986
1. CW 3986 is a synthetic variety with 59 parent plants which were selected sequentially for resistance to Phytophthora root rot, Anthracnose (race 1), and seed yield. Parent plants were selected from crosses between selections from various populations developed by a combination of phenotypic recurrent selection and strain crossing with selection for one or more of the following pests: Fusarium wilt, Verticillium wilt, anthracnose (race 1), Phytophthora root rot, blue alfalfa aphid, and spotted alfalfa aphid Parentage of CW 3986 traces to the following germplasm sources: Grasis, CW 446, Mecca, DK 189, Cibola, and Sundor. Approximate germplasm source contributions are as follows: Ladak (1%), M.varia (2%), Turkistan (11%), Flemish (1%), Chilean (9%), Peruvian (3%), Indian (17%), African (40%), and Unknown (16%).

2. CW 3986 is adapted to the Southwestern U. S. and Mexico and is intended for use in the Southwestern U. S. , Mexico, and Argentina. CW 3986 has been tested in California and Mexico.

3. CW 3986 is a very nondormant variety with fall dormancy similar to CUF 101. Flower color observed in the Syn2 generation is greater than 99% purple with a trace of variegated, white, cream, and yellow.

4. CW 3986 has high resistance to anthracnose (race 1), Fusarium wilt, Phytophthora root rot, spotted alfalfa aphid, blue alfalfa aphid, pea aphid and stem nematode and [moderate resistance to Verticillium wilt. Reaction to bacterial wilt, Aphanomyces root rot (race 1), and root knot nematode has not been adequately tested.

5. Seed increase of CW 3986 is on a limited generation basis with one generation of breeder and two generations of the foundation, and certified seed classes. Breeder (Syn. 1), foundation (Syn. 2 or Syn. 3), and certified (Syn3 or Syn. 4) classes will be recognized. Production of Syn. 3 foundation seed requires the consent of the breeder. Breeder seed was produced under open isolation near Woodland, California in 1993. 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 CW 3986 will be available in 1998.

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