1. CW 13014 is a synthetic variety with 225 parent plants that were selected sequentially for
multifoliolate leaf expression and for resistance to Phytophthora root rot, Aphanomyces root rot, and
anthracnose. Parent plants were selected from crosses between selections from two and three-year old
Wisconsin nursery selection from various populations with high resistance to stem nematode. Nursery
source plants 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, anthracnose (race 1), Leptosphaerulina leafspot, and stem nematode.
Parentage of CW 13014 traces to the following germplasm sources: WinterGold, Extreme, AlfaStar II,
Alliant, Chimo, Foremost, Prairie Max, Radiant, and miscellaneous Cal/West Seeds breeding populations.
Breeder seed (Syn.1) was produced under cage isolation near Woodland, California in 2001.
2. CW 13014 is adapted to the North Central area of the U.S. and is intended for use in the North Central,
East Central, and Winterhardy Intermountain areas of the U.S.. CW 13014 has been tested in Wisconsin
and South Dakota.
3. CW 13014 is a moderately dormant variety with fall dormancy similar to FD class 4 check varieties.
Flower color observed in the Syn.2 generation is approximately 100% purple with a trace of variegated,
white, cream, and yellow.
4. CW 13014 has high resistance to anthracnose (race 1), bacterial wilt, Verticillium wilt, and
Phytophthora root rot with resistance to Fusarium wilt, Aphanomyces root rot (race 1), spotted alfalfa
aphid, stem nematode, and northern root knot nematode. Reaction to the pea aphid and blue alfalfa aphid
has not been tested.
5. Seed increase of CW 13014 is on a limited generation basis with two generations each of breeder,
foundation, and certified seed classes. Breeder (Syn.1 or Syn.2), foundation (Syn.2 or Syn.3), and
certified (Syn.3 or Syn.4) classes will be recognized. Production of Syn.2 breeder or Syn.3 foundation
seed requires consent of the breeder. Breeder seed was produced under cage isolation near Woodland,
California in 2001. 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 13014 will be available in 2006.
7. No decision has been made regarding Plant Variety Protection.
