ABI 9032

1. ABI 9032 is a synthetic variety with 137 parent clones. Parent clones trace to 26 populations selected for resistance to the following pests: bacterial wilt, Fusarium wilt, Verticillium 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 Marshfield and Livingston, Wisconsin, based on vigor, leafhopper yellowing resistance, leaf disease resistance, winter injury and fall dormancy reaction.
Parentage traces to Nordic (14%), Venture (11%), Exp AP 8734 (10%), Exp AP 8822 (9%), Genesis (6%), Cutter, Aggressor, Dominator and Garst 645 (5% each), Trident II, Stine 9227, Horizon and Exp AP 45 (4% each), Exp AP 47 (3%), with 11% coming from numerous other sources.  Approximate germplasm source contributions are: M. falcata (8%), Ladak (8%), M. varia (20%), Turkistan (15%), Flemish (31%), Chilean (8%), Peruvian (4%) and 6% unknown.

2. ABI 9032 appears to be adapted to and is intended for use in the North Central U.S. It has been tested in Wisconsin, Iowa, Idaho and Pennsylvania.

3. Fall dormancy of ABI 9032 is similar to Ranger. Flower color of Syn 2 generation is approximately 70% purple and 30% variegated, with a trace of cream, white and yellow.

4. ABI 9032 has high resistance to bacterial wilt, Fusarium wilt, anthracnose (race 1), Phytophthora root rot and pea aphid, and resistance to Verticillium wilt and Aphanomyces (race 1). Reaction to stem nematode, spotted alfalfa aphid, blue alfalfa aphid and root knot nematode 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 variety.

6. Certified seed will be available in 1993.

7. Plant Variety Protection will not be applied for.
