1. FG 7G5 17 is a synthetic variety with 165 parent plants. Parent plants were selected for multifoliolate expression and resistance to one or more of the following disease and insect pests: Phytophthora root rot, Verticillium wilt, spotted alfalfa aphid and root knot nematode (M. hapla). Germplasm sources used ill developing FG 7G5 17 were Parade (30%), FG 6J92 (30%), Tahoe (26%) and VS-i 38 (14%). Breeder seed (Syn 1) was produced near Nampa, Idaho in 1995. Seed was harvested in total on all parents and bulked to form breeder seed. Approximate germplasm source contributions are: M. falcata (1%), Ladak (10%), M. varia (6%), Turkistan (20%), Flemish (11%), Chilean (13%), Peruvian (2%), Indian (17%), African (17%) and unknown (3%).
2. This variety is adapted to the Southwest and Moderately Winterhardy Intermountain areas. This variety has been tested in Idaho, California and Argentina It will be used in the Southwestern U. S. , high desert areas of Western U. S. and Argentina
3. This variety has fall dormancy similar to FD7 checks. Flower color (Syn2) is 100% purple. FG 7GS 17 has high multifoliolate leaf expression.
4. This variety has high resistance to Fusarium wilt, anthracnose (Race 1), Phytophthora root rot, pea aphid and spotted alfalfa aphid; resistance to Verticillium wilt and blue alfalfa aphid; and moderate resistance to bacterial wilt and stem nematode. 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 1), 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.
7. No decision has been made concerning Plant Variety Protection Act.
