1. CW 83010 is a
synthetic variety with 203 parent plants that were selected sequentially
for high winter hardiness, high forage yield, high relative feed value,
and multifoliolate leaf expression. Parent plants were selected from
three-year old Minnesota and Wisconsin yield trials and from three-year
old Wisconsin nurseries. Yield trial source varieties and nursery source
plants were selected 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 1), anthracnose (race
1), and Leptosphacru1ina leafspot. Parentage of CW 83010 traces to the
following germplasm sources: Abound (4%), Sprint (3%), Supreme (3%), DK
142 (2%), Extreme (2%), Pointer (2%), TOP HAND (2%), 512 (1%), Alliant
(1%) LegendGold (1%), Nemesis (1%), UltraLac (1%), and 2. CW 83010 is
adapted to the North Central and East Central areas of the U.S. and is
intended for use in the North Central, East Central, and Great
Plains areas of the U.S. CW 83010 bas been tested in Wisconsin,
Illinois, and Minnesota. 3. CW 83010 is a dormant variety with fall dormancy similar to FD class 3 check varieties. Flower color observed in the Syn. 2 generation is greater than 98% purple and 1% white with a trace of variegated, cream, and yellow. 4. CW 83010 has high
resistance to anthracnose (race 1), bacterial wilt, Fusarium wilt,
Phytophthora root rot, and Aphanomyces root rot (race 1) with moderate
resistance to spotted alfalfa aphid. Reaction to the Verticillium wilt,
pea aphid, blue alfalfa aphid, stem nematode, and root knot nematode bas
not been tested. 5. Seed increase
of CW 83010 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 1998.
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. 7. No decision has been
made regarding Plant Variety Protection. 8. This information can
be forwarded to the PVP office. 9.
