CW 2514


1. C/W 2514 is a synthetic variety with 365 parent plants which were selected sequentially for multifoliolate leaf expression and for resistance to Phytophthora root rot and Aphanomyces root rot (race 1). Parent plants were selected from a 21--clone polycross population where the 21 clones had been selected for high relative feed value (using Near Infrared Reflectance Spectroscopy), forage yield, multifoliolate leaf expression, and late fall dormancy from various populations which were themselves developed by phenotypic recurrent selection for multifoliolate leaf expression and for resistance to one or more of the following pests: bacterial wilt, Aphanomyces root rot (race 1), Phytophthora root rot, anthracnose (race 1), Verticillium wilt, Leptosphaerulina leafspot, and spotted alfalfa aphid. Both clonal and half-sib progeny testing were used to select the 21 clones. Parentage of C/W 2514 traces to the following germplasm sources: Alfaleaf, Jewel, VS--775, Crown II, 2833, Achieva, Pacesetter, Encore, and Prism. Approximate germplasm source contributions are as follows: M. falcata (6%), Ladak (5%), M. varia (26%), Turkistan (3%), Flemish (54%), and Chilean (6%).


2. C/W 2514 is adapted to and intended for use in the Moderately Winterhardy Intermountain, Great Plains, East Central, and Southeast regions of the U.S. C/W 2514 has been tested in California, Idaho, Oklahoma, North Carolina, and Georgia.


3. C/W 2514 is a moderately dormant variety with fall dormancy similar to DuPuits. Flower color observed in the Syn.2 generation is approximately 98% purple, 1% variegated, 1% cream, and a trace of white, and yellow. At first flower in autumn approximately 84% of the stems show multifoliolate leaf expression.


4. C/W 2514 has high resistance to bacterial wilt, with resistance to anthracnose (race 1), Fusarium wilt, Verticillium wilt, Phytophthora root rot, pea aphid, and spotted alfalfa aphid. Reaction to stem nematode, root knot nematode, blue alfalfa aphid and Aphanomyces root rot (race 1) has not been adequately tested.


5. Seed increase is on a limited generation basis with one generation of breeder and two generations of the foundation and certified seed classes. Breeder (Syn.1), 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 at Woodland, California in 1990. 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 C/W 2514 will be available in 1994.


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