ABI 700
1. ABI 700 is a synthetic variety with 47 parent plants. Parent plants trace to populations selected for resistance to the following pests: bacterial wilt, Fusarium wilt, Verticillium wilt, Phytophthora root rot, anthracnose, blue alfalfa aphid, spotted alfalfa aphid, stem nematode and northern root knot nematode. Phenotypic recurrent selection was used. Final selections were made from 2 populations in a 3-year-old space-plant nursery near Nampa, Idaho based on vigor, winter survival, color and degree of fall dormancy. Parentage traces predominantly to Diamond (50%),Oregon GXC (18%), Oregon GXE (18%), Apollo II (4%), Trident (3%) Endure (2%), Apollo (1%), Maverick (l%), and Atlas (1%), with 2% from numerous sources. Approximate germplasm source contributions are: M. falcata (3%), Ladak (4%), M. varia (15%), Turkistan (18%), Flemish (26%), Chilean (7%) Peruvian (2%), Indian (3%), African (1%) and unknown (21 %). 2. ABI 700 is adapted to and is intended for use in the areas of the Pacific Northwest and California where moderately dormant varieties are used for hay, production. It has been tested in California and Idaho. 3. Fall dormancy of ABI 700 is similar to Lahontan. Flower color is approximately 89% purple and 11 variegated with a trace of white, yellow and cream. 4. ABI 700 has high resistance to Fusarium wilt, spotted alfalfa aphid, blue alfalfa aphid, pea aphid and anthracnose (Race 1), resistance to Phytophthora root rot and stem nematode and moderate resistance to bacterial wilt, Verticillium wilt and northern root knot nematode. 5. Seed increase is limited to one generation each of breeder, foundation and certified 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 San Joaquin Valley of California. 6. Certified seed will be available in 1991. 7. Plant Variety Protection will not be applied for. 8. This information can be forwarded to the PVP office.
