1. ZX 9382 is a synthetic variety with 400 parent clones. Parent clones trace to two populations selected for resistance to Phytophthora root rot, anthracnose (race l),bacterial wilt, Fusarium wilt, Verticillium wilt, blue alfalfa aphid, spotted alfalfa aphid, and pea aphid, stem nematode southern root knot nematode and crown rot. Recurrent phenotypic selection was used. Final selections were made from seven year old field near Los Banos, California based on general root and crown health.
1a. Parentage traces to Experimentals closely related to GI 13R Plus (95%), and unknown (5%). Breeder seed (Syn 1) was produced on parental clones near Nampa, Idaho in 1993 under field conditions. Approximate germplasm source contributes are: M. falcata (1%), Ladak (1%), M. varia (2%), Turkistan (25%), Flemish (1%), Chilean (2%), Peruvian 1%), Indian (2%), African (60%) and unknown (5%).
2. ZX 9382 is intended for use in central and southern California, and the lower elevations of Arizona and New Mexico. Zx 9382 has been tested in California.
3. Fall dormancy is similar to Moapa 69. Flower color in Syn 2 generation is 98% purple, 1% variegated with less than 1% cream, white and yellow.
4. ZX 9382 has high resistance to Fusarium Wilt, and Phytophthora Root Rot; resistance to Pea Aphid, and Stem Nematode; moderate resistance to Spotted Alfalfa Aphid, and the Blue Alfalfa Aphid; low resistance to Verticillium Wilt
5. Seed increase is limited to one generation each of breeder (Syn 1), foundation (Syn 2) and certified (Syn 3) seed classes. Certified seed 'nay 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.
