CW 94008

 

1. CW 94008 is a synthetic variety with 200 parent plants that were selected sequentially for high winter hardiness, large deep-set crowns and multifoliolate leaf expression. Parent plants were selected from five-year old Pennsylvania and three-year old Wisconsin yield trials. Yield trial source varieties were derived from various populations that were developed by phenotypic recurrent selection for high relative feed value (using Near Infrared Reflectance Spectroscopy), and for resistance to one or more of the following pests: bacterial wilt. Fusarium Wilt. Verticillium wilt, Phytophthora root rot, Aphanomyces root rot (race I), anthracnose (race I), and Leptosphaerulina leafspot. Parentage of CW 94008 traces to the following germplasm sources: BigHorn, Hunter, DK 133, WinterGold, 9429, Alliant, HayMaker II, Trialfalon, Stallion, Cyclone, and miscellaneous Cal/West Seeds breeding populations. Approximate germplasm source contributions are as follows: M. falcata (6%), Ladak (5%), M. varia (27%), Turkistan (5%), Flemish (50%), and Chilean (7%).

2. CW 94008 is adapted to and intended for use in the North Central, East Central, and Great Plains areas of the U.S. CW 94008 has been tested in Wisconsin, Iowa, Minnesota, South Dakota, Nebraska, Pennsylvania, and New York.

3. CW 94008 is a moderately dormant variety with fall dormancy similar to FD class 4 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 94008 has high resistance to anthracnose (race 1), bacterial wilt, Fusarium wilt, Phytophthora root rot, and stem nematode, with resistance to pea aphid, Aphanomyces root rot (race 1), and northern root knot nematode (Meloidogyne hapla). Reaction to Verticillium wilt, spotted alfalfa aphid, and blue alfalfa aphid has not been tested

5. Seed increase of CW 94008 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 Woodland, 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 94008 will be available in 2003.

7. No decision has been made regarding P1ant Variety Protection.
