2980

1.   2980 is a synthetic variety with 225 parent plants. Parent plants trace to various populations selected for resistance to Aphanomyces root rot and one or more of the following pests: bacterial wilt, Verticillium wilt, anthracnose, Phytophthora root rot, Leptosphaerulina leafspot, and spotted alfalfa aphid. Phenotypic recurrent selection was used. Parentage traces predominately (in order of contribution) to 98, Crown, Apollo II, Summit, Centurion, Endure, G-2852, and DK-125. Approximate germplasm source contributions are: M. falcata - 6%, Ladak - 6%, M. varia - 28%, Turkistan - 3%, Flemish - 52%, and Chilean - 5%.

2.   2980 is intended for use in the north central and northeastern U.S. for hay, haylage, greenehop or dehy production. It has been tested in Wisconsin, New York and Pennsylvania.

3.   2980 is a dormant variety. Fall dormancy is similar to Ranger. Flower color is 78% purple and 22% variegated, with a trace of white, yellow and cream.

4.   2980 has high resistance to bacterial wilt and Phytophthora root rot with resistance to Aphanomyces root rot, anthracnose, Fusarium wilt, Verticillium wilt, pea aphid and spotted alfalfa aphid. 2980 has significant resistance to Leptosphaerulina leafspot but actual percentage resistant plants has not been determined. Reaction to stem nematode and blue alfalfa aphid has not been adequately tested.

5.   Seed increase is on a limited generation basis with one generation each of breeder and certified seed classes, and two generations of foundation seed. 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 the consent of the breeder. Breeder seed was produced under cage isolation at Woodland, CA. Sufficient foundation seed for the projected life of the variety will be maintained by VISTA. Stands of foundation and certified seed fields are limited to 3 and 6 years, respectively.

6.   Certified seed will be marketed in 1990.

7.   No decision has been made concerning Plant Variety Protection.

8.   This information can be forwarded to the PVP office.
