1. Amerigraze 701 is a synthetic variety with 175 parent clones. Parent clones trace to one population selected for grazing tolerance. verticillium wilt, spotted alfalfa aphid, blue alfalfa aphid, and pea aphid. Phenotypic recurrent selection was used. Final selections were made from a grazing survival trial at Tifton Georgia. Parentage traces to Pecos ( 100%). Approximate germplasm source contributes are: M falcata (2%), Ladak (1%), M.varia (7%), Turkistan(25%), Flemish(2%), Chilean(15%), Peruvian(1%), Indian (15%), African (2%), and unknown (30%). Breeder seed (Syn 1) was produced under field isolation near Nampa, Idaho in 1993.
2. Amerigraze 701 is adapted to the San Joaquin Valley. CA where it has been tested and is intended for use.
3. Fall dormancy is similar to Mesilla. Flower color is of (Syn 2) approximately 95% purple and 4% variegated with a trace of white, cream. and yellow. After intensive grazing, Amerigraze 701 showed plant survival significantly better than the unselected varieties Pecos and Florida 77.
4. Amerigraze 701 has high resistance to bacterial wilt, fusarium wilt, and southern root knot nematode; resistant to anthracnose (Race 1), verticillium wilt, phytophthora root rot, spotted alfalfa aphid, and blue alfalfa aphid; moderate resistance stem nematode, and pea aphid.
5. Seed increase is limited to one generation each of breeder (Syn 1), two generations of foundation and two to three generations of certified. 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 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.
