C316
1. C316 is a 198-plant synthetic variety resulting from phenotypic recurrent selection for resistance to Phytophthora root rot. Parental germplasm traces to ABT 350 and Paramount. Approximate germplasm source contributions are M. falcata (14%), Ladak (23%), M. varia (27%), Turkistan (5%), and Flemish (31%).
2. C316 is adapted for use in the north central and east central regions of the United States. C316 has been yield tested in Illinois, Pennsylvania, and Wisconsin.
3. Flower color of C316 at syn2 approximates 100% purple with a trace of yellow, variegated and white. The fall dormancy of C316 is similar to Legend (Class 4).
4. C316 has high resistance to anthracnose (race 1), bacterial wilt, Fusarium wilt, Verticillium wilt, and Aphanomyces root rot (race 1); and resistance to Phytophthom root rot and pea aphid. Reaction to stem nematode, blue alfalfa aphid, spotted alfalfa aphid and root knot nematode has not been adequately tested.
5. Breeder seed (syn1) was produced in 1996 on 198 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.
