CW 99112

CW 99112

1. CW 99112 is a synthetic variety with 61 parent plants which were selected for lygus tolerance and seed yield from space planted nurseries in California. Parent plants were selected from various populations which were developed by selecting for aphid resistance, drought tolerance, frost tolerance, persistence and agronomic characteristics from space planted nurseries and yield trials in Argentina. Parentage of CW 99112 traces to miscellaneous Cal/West Seeds breeding populations (100%). Approximate germplasm source contributions are as follows: M. varia (4%), Turkistan (10%), Flemish (4%), Chilean (10%), Peruvian (4%), Indian (25%), and African (43%).

2. CW 99112 is adapted to and intended for use in the Southwest area of the U.S., Mexico, and Argentina CW 99112 bas been tested in California, Mexico, and Argentina.

3. CW 99112 is a very nondormant variety with fall dormancy similar to FD class 9 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 99112 bas high resistance to Fusarium wilt, blue alfalfa aphid, and stem nematode, with resistance to anthracnose (race 1), Phytophthora root rot, and spotted alfalfa aphid. Reaction to bacterial wilt, Verticillium wilt, Aphanomyces root rot (race 1), pea aphid, and root knot nematode has not been adequately tested.

5. Seed increase of CW 99112 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 open isolation near Tranquility, California in 1999. 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 99112 will be available in 2003

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