1. ZX 9362 is a synthetic variety with 200 parent clones. Parent clones trace to two populations selected for resistance to Verticillium wilt, anthracnose (Race 1), spotted alfalfa aphid, blue alfalfa aphid, pea aphid, and stem nematode, Phenotypic recurrent selection was used. Final selections were made from a space - planted nursery near Nampa, Idaho. Parentage traces to Lobo (90%) and unknown (10%). Approximate germplasm source contributions are: M. falcata (6%), Ladak: (6%), M. varia (19%), Turkistan (12%), Flemish (31%), Chilean (9%), Peruvian (2%), Indian (2%), African (1%), and unknown (12%). Breeder seed (Syn 1) was -Iced under field isolation near Nampa, Idaho in 1991.
2. ZX 9362 is intended for use in areas of the Northwest San Joaquin Valley of California, to the Sacramento valley and coastal valleys of Southern California and intermediate and high desert valleys of Southern California, Arizona, Nevada and the lower elevations of Idaho, Utah, Oregon and Washington. ZX 9362 has been tested in California and Idaho.
3. Fall dormancy is similar to Lahontan. Flower color in Syn 2 generation is 88% purple, 11% variegated with less than 1% each of cream, white and yellow.
4. ZX 9362 has high resistance to Verticillium Wilt, Fusarium Wilt, and Columbia Root Knot Nematode; resistance to Anthracnose (Race 1), Bacterial Wilt, Phytophthora Root Rot, Spotted Alfalfa Aphid, Pea Aphid, Stem Nematode, and Northern Root Knot Nematode; moderate resistance to the Blue Alfalfa Aphid.
5. Seed increase is limited to one generation each of breeder (Syn 1), foundation (Syn 2) and certified (Syn 3) seed classes. Certified seed may be produced from either breeder or foundation classes. A 1,3 an 5 year stand life is permitted on fields producing breeder, foundation and certified classes, respectively. Foundation seed production, outside the area of adaptation is limited to single-season production (non-overwintering). Second year of production may be allowed with inspection and approval by breeder prior to second year production. Breeder seed was produced in 1993. ABI will maintain sufficient stocks for the projected life of the variety.
6. Certified seed will be available in 1998
7. Plant variety protection will not be applied for.
