1. ZG 9490 is a synthetic variety with 190 parent clones. Parent clones trace to two populations selected for resistance verticillium wilt. Anthracnose (Race 1), spotted alfalfa aphid, blue alfalfa aphid, pea aphid, southern root knot nematode and survival under intense grazing pressure by beef cattle. Phenotypic recurrent selection was used. Final selections were made from a grazing survival trial at Tifton Georgia. Parentage traces to Cuf 101 (80%), and non-dormant experimental populations (20%). Approximate germplasm source contributions are: M.falcata (0%), Ladak (1%), M.varia (2%), Turkistan(11%), Flemish(1%), Chilean (7%), Peruvian(2%), Indian (23%), African (53%), Arabian (0%), and unknown (0%). Breeder seed (Syn 1) was produced under field isolation near Nampa, Idaho in 1993.
2. ZG 9490 is intended for use in the Southwestern region of the U.S. It has tested in California and Arizona.
3. Fall dormancy of ZG 9490 is similar to Moapa 69. Flower color of 98% purple, and 1% variegated a trace of cream, yellow and white.
4. ZG 9490 has high resistance to fusarium wilt; resistance to bacterial wilt, spotted alfalfa aphid, pea aphid, blue alfalfa aphid, stem nematode. and southern root knot nematode; moderate resistance verticillium wilt, phytophthora root rot, and anthracnose (Race 1).
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 adaptation, is limited to single-season production (non- overwintering). Second year of production maybe allowed with inspection and approval by breeder prior second year of productions. 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 1997
7. Plant variety protection will not be applied for.
