1. C207 is a 180-plant synthetic variety resulting from phenotypic recurrent selection for resistance to Phytophthora root rot. Parental germplasm traces to GH755, WL 324, Ovation and Trident Il. Approximate germplasm source contributions are M. falcata (12%), Ladak (18%), M. varia (21%), Turkistan (17%), and Flemish (32%).
2. C207 is adapted for use in the north central and east central regions of the United States has been yield tested in New York and Wisconsin.
3. Flower color of C207 at syn2 approximates 100% purple with a trace of variegated and white. The fall dormancy of C207 is similar to Pioneer 5246 (Class 3).
4. C207 has high resistance to anthracnose (Race 1), bacterial wilt, Fusarium wilt, Verticillium wilt, Phytophthora root rot, and Aphanomyces root rot (Race 1); resistance to spotted alfalfa aphid and moderate resistance to pea aphid. Reaction to blue alfalfa aphid, stem nematode and root knot nematode has not been adequately tested.
5. Breeder seed (syn1) was produced in 1995 on 180 plants under cage isolation at Bakersfield, California. Sufficient foundation (syn2) seed will be produced for the expected life of the variety and will be maintained by W-L Research. One generation of breeder (syn1), two generations of foundation (syn2 or 3), and three generations of certified (syn2, 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 syn3 foundation seed requires consent of the breeder.
6. Certified seed will be marketed in 2000.
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.
