1. FG 8G521 is a synthetic variety with 120 parent plants. Parent plants were selected for persistence and resistance to one or more of the following: Phytophthora root rot, Verticillium wilt, spotted alfalfa aphid. Germplasm sources used in developing FG 8G52 I were Sundor (20%), WL 516 (24%), Yolo (14%), Diamond (14%) and DK189 (28%). Seed was harvested in total on all parents and bulked to form breeder seed. Approximate germplasm source contributions are: M. falcata (1%), Ladak (2%), M. varia (5%), Turkistan (15%), Flemish (3%), Chilean (11%), Peruvian (1%), Indian (20%), African (35%) and unknown (7%).

Reaction to Aphanomyces root rot and root knot nematode has not been tested.

5. Seed increase is on a limited generation basis with one generation of breeder and two generations of foundation and certified seed classes. Breeder (Syn I), foundation (Syn 2 or Syn 3), and certified (Syn 3 or Syn 4) classes will be recognized. Production of Syn 3 foundation seed requires consent of the breeder. Breeder seed was produced near Nampa, Idaho in 1995. Sufficient foundation seed for the projected life of the variety will be maintained by Forage Genetics. Stands of foundation and certified seed fields are limited to 3 and 6 years, respectively.

6. Certified seed will be marketed in 1998.
