CW 78122 

1. CW 78122 is a synthetic variety with 202 parent plants which were selected for aphid resistance, drought tolerance, frost tolerance, persistence and agronomic characteristics from space planted nurseries and yield trials in Argentina. Parent plants were selected from various populations which were developed by a combination of phenotypic recurrent selection and strain crossing with selection for resistance to one or more of the following pests: Fusarium wilt, Verticillium wilt, Phytophthora root rot, anthracnose (race 1), spotted alfalfa aphid, blue alfalfa aphid, and stem nematode. Parentage of CW 78122 traces to Activa, DK 189, Topacio, ACA 900, F969, 13 R Supreme, Yolo, Super Supreme, Grasis, DK 191,5715, WL 516, WL 457, and misce1laneous Cal/West Seeds breeding populations. Approximate germplasm source contributions are as follows: M. varia (4%), Turkistan (17%), Flemish (7%), Chilean (8%), Peruvian (4%), Indian (23%), and African (37%).

2. CW 78122 is adapted to and intended for use in the Southwest area of the U.S. and Argentina. CW 78122 has been tested in California, New Mexico, and Argentina.

3. CW 78122 is a nondormant variety with fall dormancy similar to FD class 8 check varieties. Flower color observed in the Syn. 2 generation is greater than 99% purple with a trace of variegated, white, cream, and yellow.

4. CW 78122 bas high resistance to anthracnose (race 1), Fusarium wilt, Phytophthora root rot, pea aphid, spotted alfalfa aphid, blue alfalfa aphid, and southern root knot nematode (Meloidogyne incognita), with resistance to Verticillium wilt and stem nematode, and moderate resistance to northern root knot nematode (Meloidogyne hapla).  Reaction to bacterial wilt and Aphanomyces root rot (race 1) has not been adequately tested.

5. Seed increase of CW 78122 is on a limited generation basis with one generation of breeder and two generations of the foundation and certified seed classes. Breeder (Syn. l), foundation (Syn. 2 or Syn. 3), and certified (Syn. 3 or Syn. 4) classes will be recognized.  Production of Syn. 3 foundation seed requires consent of the breeder. Breeder seed was produced under cage isolation near Mendoza, Argentina in 1997. 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 78122 will be available in 2003.

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