1. AP 8871 is a synthetic variety with 145 parent clones. Parent clones trace to 5 populations selected for resistance to Verticillium wilt, anthracnose (Race 1), spotted alfalfa aphid and blue alfalfa aphid. Phenotypic recurrent selection was used. Final selections were made from a space-planted nursery near Kingsburg, California. Parentage of AP 8871 traces to GT 13R Plus (33%), Diamond (16%), Baron (6%) and various other non-dormant germplasm (45%). Approximate germplasm source contributions are: M. falcata (1%), Ladak (2%), M. varia (3%), Turkistan (14%), Flemish (6%), Chilean (1%), Peruvian (1%), Indian (1%), African (25%) and 45% unknown. Breeder seed (Syn 1) was produced on cuttings of the parental clones near Nampa, ID, in 1988. An equal number of cuttings (approximately 20) of each parental clone was transplanted at random into an isolated block and harvested in bulk.
2. AP 8871 appears to be adapted to areas of central and southern California and is intended for use in central and southern California and lower elevations of Arizona and New Mexico. It has been tested in California.
3. Fall dormancy of AP 8871 is similar to Mesilla. Flower color of Syn 2 generation is approximately 95% purple and 5% variegated, with a trace of cream, white and yellow.
4. AP 8871 has high resistance to Fusarium wilt and southern root knot nematode (m. incognita); resistance to anthracnose (Race 1), bacterial wilt, Verticillium wilt, Phytophthora root rot, pea aphid and blue alfalfa aphid; and moderate resistance to stem nematode. Reaction to spotted alfalfa aphid and Aphanomyces root rot has not been determined.
5.Seed increase is limited to one generation each of breeder (Syn 1), foundation (Syn 2) and certified (Syn 2 or 3) seed classes. Certified seed may be produced from either breeder or foundation classes. A 1, 3 and 5-year stand life is permitted on fields producing breeder, foundation and certified classes, respectively. Foundation seed production, outside the southern adaptation area, is limited to single-season production (non-overwintering). Second year of production may be allowed with inspection and approval by breeder prior to second year of production. Breeder seed was produced in 1988. ABI will maintain sufficient seed stocks for the projected life of the variety.
6. Certified seed will be available in 1994.
7. Plant Variety Protection will not be applied for.
