Recurrent phenotypic selection was used. Syn1 seed was produced near Nampa, ID in 1995, harvested in total on all parents and bulked to form breeder seed. This variety is adapted to the North Central United States and intended for use in the North Central, East Central, Moderately Winterhardy Intermountain and Great Plains of the United States. This variety has been tested in Wisconsin, Minnesota and Iowa. This variety has fall dormancy similar to FD4 checks and winter survival similar to WS2 checks.
Geneva has high multifoliolate leaf expression.
Reaction to root knot nematode has not been tested. Seed increase is on a limited generation basis with one generation of breeder and two generations of foundation and certified seed classes. Production of Syn3 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.
