1. C133 is a 135-plant synthetic variety resulting from phenotypic recurrent selection for resistance to Phytophthora root rot and Aphanomyces root rot (Race 1). Parental germplasm traces to WL 324, Garst 636, Pioneer 532, and Royalty. Approximate germplasm source contributions are: M. falcata (17%); Ladak (18%); M. varia (31%); Turkistan(14%); and Flemish (20%).
2. C133 is adapted for use in the North Central and East Central regions of the U.S. C133 has been yield tested in Illinois, Pennsylvania, and Wisconsin.
3. Flower color of C133 at Syn 2 approximates 98% purple and 2% variegated with traces of cream and white. The fall dormancy of C133 is similar to Vernal (Class 2).
4. C133 has high resistance to anthracnose (Race 1), bacterial wilt, Fusariurn wilt, Verticillium wilt, Phytophthora root rot, and Aphanomyces root rot (Race 1); resistance to pea aphid, spotted alfalfa aphid, and blue alfalfa aphid; and moderate resistance to stem nematode. Reaction to root knot nematode has not been adequately tested.
5. Breeder seed (Syn 1) was produced in 1994 on 135 plants at Bakersfield, CA. 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 3 and 5 years, respectively. Foundation seed must be produced above 40 degrees North latitude. Production of Syn 3 Foundation seed requires consent of the breeder.
6. Certified seed will be marketed in 1997.
7. It is undecided whether application will be made for Plant Variety Protection.
8. The information in this application can be turned over to the PVP office.
9. Experimental Designation: C133 Date Submitted: December 1996
