1. AB1 9193 is a synthetic variety with 200 parental clones. Parent clones trace populations selected for resistance to phvtophthora root rot, anthracnose, bacterial wilt, fusarium wilt, verticillium wilt, blue alfalfa aphid, spotted alfalfa aphid, pea aphid, stem nematode northern root knot nematode. Recurrent phenotypic selection was used. Final selections were made from two and three year old nurseries near Nampa, Idaho based on overall root and crown health. Parentage traces to experimentals closely related to GT 13R +(60%), Cuf 101 (20%), Hasawi (5%), Ardiente (5%), Yolo (5%) and unknown sources (5%). Breeder seed (Syn l ) was produced on cuttings of the parental clones near Nampa, Idaho in 1991, under field isolation. Approximate germplasm source contributes are: M. falcata (1%), M. varia ( 1%), Turkistan (20%), Flemish (1%), Chilean ( 1%), Peruvian (1%), Indian (1%), and African (68%), Arabian (1%), and unknown (5%).
2. ABI 9193 is adapted to the southwest and is intended for use in Central and Southern California and lower elevations of Arizona and New Mexico. It has tested in California, Arizona.
3. Fall dormancy is similar to Moapa 69. Flower color of Syn 2 generations is approximately 99% purple with a trace of variegated, cream, yellow, and white.
4. ABI 9193 has high resistance to fusarium wilt, and the spotted alfalfa aphid: resistance to anthracnose, phytophthora root rot, pea aphid, blue alfalfa aphid and southern root knot nematode. Moderate resistance bacterial wilt, verticillium wilt, and stem nematode.
5. Seed increase is limited to one generation each of breeder (Syn I), foundation (Syn 2) and certified (Syn 3) seed classes. certified seed may be produced from either breeder or foundation classes. A 1, 3 and 5 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 1991. 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.
