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 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. 8. This information can
be forwarded to the PVP office. 9.
