1. The selection criteria used in the development of this variety includeforage yield potential,forage quality potential, persistence, and resistanceto one or more of the following pests:bacterial wilt, Verticillium wilt,Fusarium wilt, anthracnose (race 1), Phytophthora root rot andAphanomycesroot rot (race 1).
2. This variety is adapted to north central and east central U. S. regions.This variety has beentested in Wisconsin and Illinois and is intended foruse in-the north central and east central U. S.regions.
3. Test variety is a moderately dormant variety, similar to FD4 checks.Test variety is very winterhardy, similar to WS2 checks. Flower color (syn2)is 93% purple, 5% variegated, 1% white, 1%yellow, with a trace of cream.This variety has high multifoliolate leaf expression.
4. This variety has high resistance to anthracnose (race 1), bacterialwilt, Fusarium wilt,Verticillium wilt, Aphanomyces root rot (race 1) andPhytophthora root rot, and moderateresistance to alfalfa stem nematode andspotted alfalfa aphid. Reaction to pea aphid, blue alfalfaaphid and root-knotnematode has not been tested.
5. Seed increase is on a limited generation basis with one generationof breeder, and twogenerations of foundation and certified seed classes.Breeder (syn1), foundation (syn2 or 3), andcertified (syn3 or 4), classeswill be recognized. Production of syn3 foundation seed requiresconsent ofthe breeder. Breeder seed was produced near Nampa, Idaho, in 1996. Sufficientfoundation seed for the projected life of the variety will be maintainedby Forage Genetics.Stands of foundation and certified seed fields are limitedto three and six years, respectively.
6. Certified seed will be marketed in 2000.
