1. AP 9089 is a synthetic variety with 400 parental clones. Parent clones trace to two populations selected for resistance to phytophthora root rot, anthracnose, bacterial wilt, fusarium wilt, verticillium wilt, blue alfalfa aphid, spotted alfalfa aphid, pea aphid stem nematode, southern root knot nematode and crown rot. Recurrent phenotypic selection was used. Final selections were made from two and three year old field nurseries near Kingsburg California, based on overall root and crown health. Parentage traces to experimentals closely related to 13R Supreme (75%) and Pecos (25%). Breeder seed (Syn 1) was produced on parental clones near Kingsburg, California, in 1990 under field isolation. Approximate germplasm source contributions are: M.falcata (1%), Ladak (1%), M.varia (2%), Turkistan(25%), Flemish (1%), Chilean(2%), Peruvian(1%), Indian (2%), and African (65%).
2. AP 9089 is intended for use in the southwestern U.S. It has been tested in California.
3. Fall dormancy of AP 9089 is similar to Moapa 69. Flower color is approximately 98% purple and 1% variegated with a trace of cream, yellow, and white.
4. AP 9089 has high resistance to fusarium wilt; resistance to bacterial wilt, anthracnose, phytophthora root rot, spotted alfalfa aphid, and southern root knot nematode; moderate resistance to verticillium wilt, pea aphid, blue alfalfa aphid, and the stem nematode.
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 and 6 year stand life is permitted on fields producing breeder, foundation and certified classes, respectively. Foundation seed production, outside the area of adaption, 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 1990. ABI will maintain sufficient stocks for the projected life of the variety.
6. Certified seed will be available in 1997.
7. Plant variety protection will not be applied for.
