AMENDMENT SUMMARY --
accepted 1994
1) 84 CaD is a 195-plant synthetic variety resulting from phenotypic recurrent selection for resistance to stem nematode. Parental plants were derived from seven experimental lines that had been selected for persistence in a test plot at Bakersfield, CA. Subsequent selection was performed for resistance to Phytophthora root rot and blue alfalfa aphid. Parental gerrnplasm traces to WL 512. WL 450, WL 504, WL 514. and WL 600. Approximate germ-plasm source contributions are: Ladak - 3%; M. vans - 5%; Turkistan -10%; Flemish - 3%; Chilean - 15%; Peruvian - 4%; Indian - 30%; and African - 30%. 2) 84 CaD is adapted to California and is intended for use in the southwestern U.S. 84 CaD has been yield tested in California. 3) 84 CaD is a non-dormant variety with fall dormency similar to Moapa 69. Flower color at Syn 2 is 99% purple and 1% cream with traces of variegated and white. 4) 84 CaD has high resistance to Fusarium wilt and pea aphid; and resistance to bacterial wilt, Phytophthora root rot, stem nematode, spotted alfalfa aphid, and blue alfalfa aphid. Reaction to anthracnose (Race 1), Vertic~llium wilt, Aphanomyces root rot (Race 1) and root knot nematode has not been adequately tested. 5) Breeder seed (Syn 1) was producsd in 1984 on 195 plants under cace isolaticn at Bakersfield, CA. Sufficient Foundation (Syn 2) seed was produced near Corcoran, CA 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. Production of Syn 3 Foundation seed requires consent of the breeder. 6) Certified seed will be marketed in 1993. 7) It is undecided whether application will be made for Plant Variety Protection. 8) The information in this application is available to the PVP office.
