CW 1361

1. C/W 1361 is a synthetic variety with 263 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 various populations that were 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 leaf spot, and spotted alfalfa aphid. Parentage of C/W 1361 traces to the following germplasm sources: Alfaleaf, Chief, VS-775, Encore, DK 122, Crown II, Achieva, and Prism. Approximate germplasm source contributions are as follows: M. falcata (7%), Ladak (6%), M. varia (27%), Turkistan (5%), Flemish (46%), and Chilean (9%).

2. C/W 1361 is adapted to the northcentral and northeastern U.S. and is intended for use in the northern and central U.S. C/W 1361 has been tested in Wisconsin, Minnesota, and Pennsylvania.

3. C/W 1361 is a dormant variety with fall dormancy similar to Ranger. Flower color observed in the Syn. 2 generation is approximately 96% purple, 4% variegated, and a trace of white, cream, and yellow. At first flower in autumn approximately 77% of the stems show multifoliolate leaf expression.

4. C/W 1361 has high resistance to bacterial wilt, Fusarium wilt, anthracnose (race 1), and Phytophthora root rot, with resistance to Verticillium wilt, Aphanomyces root rot (race 1), stem nematode, and spotted alfalfa aphid. Reaction to root knot nematode, pea aphid, and blue alfalfa aphid 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 1991. 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 1361 will be available in 1994.

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