C227

 

 

  1. C227 is a 132-plant synthetic variety resulting from phenotypic recurrent selection for resistance to Phytophthora root rot and Aphanomyces root rot (Race 1). Parental germplasm traces to Paramount, Royalty, WL 252 HQ, WL 316 and WL 324. Approximate germplasm source contributions are M. falcata – 16%, Ladak – 19%, M. varia – 30%, Turkistan – 15% and Flemish – 20%.

  1. C227 is adapted for use in the North Central, East Central and moderately winterhardy intermountain regions of the United States. C227 has been yield tested in New York, Washington and Wisconsin.

  1. Flower color of C227 at Syn 2 approximates 100% purple with a trace of variegated and white. The fall dormancy of C227 is similar to Vernal (Class 2).

  1. C227 has high resistance to anthracnose (Race 1), bacterial wilt, Fusarium wilt and Aphanomyces root rot (Race 1); and resistance to stem nematode, pea aphid and spotted alfalfa aphid. Reaction to blue alfalfa aphid, Verticillium wilt, Phytophthora root rot and root knot nematode has not been adequately tested.

  1. Breeder seed (Syn 1) was produced in 1995 on 132 plants under cage isolation at Bakersfield, California. Sufficient foundation (Syn 2) seed will be produced for the expected life of the variety and will be maintained by W-L Research. One generation of Breeder (Syn 1) and two generations each of Foundation (Syn 2 or 3) and Certified (Syn 3 or 4) seed are recognized. The maximum permitted length of stand for Foundation and Certified seed fields are three and five years, respectively. Foundation seed must be produced above 40 degrees North latitude. Production of Syn 3 Foundation seed requires consent of the breeder.

  1. Certified seed will be marketed in 1999.

  1. It is undecided whether application will be made for Plant Variety Protection.

  1. The information in this application can be turned over to the PVP office.

  1. Experimental Designation: C227 Date Submitted: November, 1998
