1. Sequoia is a 235-plant synthetic variety resulting from phenotypic recurrent selection for stem nematode. Source material traces to elite WL germplasm selected for yield and persistence from field yield trials at Bakersfield, California. Parental germplasm traces to WL 457, WL 514 and Cuf 101. Approximate germplasm source contributions are Arabian - 50%, Chilean - 10%, Indian 10%, African - 20% and Peruvian - 10%. 2. Sequoia is adapted to and intended for use in the Southwestern United States. Sequoia has been yield tested in California. 3. Flower color of Sequoia at Syn 2 approximates 100% purple with traces of cream, white and variegated. The fall dormancy of Sequoia is similar to Cuf 101 (Group 9). 4. Sequoia has high resistance to Fusarium wilt, stem nematode, spotted alfalfa aphid, blue alfalfa aphid and southern root knot nematode; and resistance to bacterial wilt, Phytophthora root rot, pea aphid and northern root knot nematode. Reaction to anthracnose, Verticillium wilt and Aphanomyces root rot (Race 1) has not been adequately tested. 5. Breeder seed (Syn 1) was produced in 1992 on 235 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. Production of Syn 3 Foundation seed requires consent of the breeder. 6. Certified seed will be marketed in 1999. 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.
