ABI 9030 (Amended)
02/01/94

1. ABI 9030 is a synthetic variety with 69 parent clones. Parent clones trace to 7 populations selected for resistance to the foilowing pests: bacterial wilt, Fusarium wilt, Verticilhium wilt, Phytophthora root rot, anthracnose and Aphanomyces. Phenotypic recurrent selection was used. Final selections were made from 2-year-old space-plant selection nurseries at Marshfleld and Livingston, Wisconsin, based on vigor, leafhopper yeliowing resistance, leaf disease resistance, winter ix~juiy and fall dormancy reaction. Parentage traces to Horizon (22%), Exp AP 45 (20%), Exp AP 47 (16%), Apoflo (16%), Anchor (5%), Blazer (3%), Peak (3%), Venus (2%), Riley (2%), Iroquois, Baker, Spredor, and VIctoria (1% each) with 7/. from numerous other sources. Approximate germplasm source contributions are:~ (7%), Ladak (8%), ~Lx~~in (18%), Turkistan (90/.), Flemish (32%), Chilean (11%), Peruvian (3%) and 12% unknown.

2. ABI 9030 appears to be adapted to and is intended for use in the North Central U.S. It has been tested in Wisconsin, Iowa and Indiana.

3. Fall dormancy of ABI 9030 is similar to Ranger. Flower color of Syn 2 generation is approximately 73% purple and 27% variegated, with a trace of cream, white and yellow.

4. ABI 9030 has high resistance to Fusarium wilt and pea aphid, and resistance to bacterial wilt, Verticillium wilt, anthracnose (race 1), Phytophthora root rot, Aphanomyces (race 1) and stem nernatode. Reaction to spatted alfalfa aphid, blue alfalfa aphid and root knot nernatode has not been determined.

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 is limited to the Pacific Northwest. Breeder seed was produced in 1990. ABI will maintain sufficient seed stocks for the projected life of the vanety.

6. Certified seed will be available in 1993.

7. Plant Variety Protection will not be applied for.

8. This information can be forwarded to the PVP office.
