Fertilac 804

1.  Fertilac 804 is a synthetic variety with 250 parent clones. Parent clones trace to four populations selected for resistance to Verticillium wilt, anthracnose (Race 1), spotted alfalfa aphid, blue alfalfa aphid, and pea aphid. Phenotypic recurrent selection was used. Final selections were made from a space planted nursery near Kingsburg, California. Parentage traces UC 176 (25%), UC 196 (25%), UC 226 (25%), and CUF 101 (25%). Approximate germplasm source contributes are: M. falcata (2%), Ladak (l%), M. varia (1%), Turkistan (20%), Flemish (1%), Chilean (10%), Peruvian (1%), Indian (14%), African (50%). Breeder seed (Syn 1) was produced under field isolation near Nampa, Idaho in 1993.

2.  Fertilac 804 is intended for use in central and Southern California, and lower elevations of Arizona and New Mexico. This variety has been tested in California.

3.  Fall dormancy is similar to CUF 101. Flower color in Syn 2 generation is 99% purple with less than 1% each of variegated cream, white and yellow.

4.  Fertilac 804 has high resistance to Fusarium Wilt, Spotted A1falfa Aphid. and Blue Alfalfa Aphid, resistance to Anthracnose (Race 1), Phytophthora Root Rot, Pea Aphid, Southern Root Rot Nematode; moderate resistance to Bacterial Wilt, Verticillium Wilt, and Stem Nematode.

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 5 year stand life is permitted on fields producing breeder, foundation and certified classes, respectively. Foundation seed production, outside the area of adaptation 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 production. 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 2004.

7.  Plant variety protection will not be applied for.
