1. The selection criteria used in the development of this variety include forage yield potential, forage quality potential, persistence, and resistance to one or more of the following pests: bacterial wilt, Verticillium wilt, Fusarium wilt, anthracnose (Race 1), Phytophthora root rot and Aphanomyces root rot (Race 1).

2. This variety is adapted to North Central and East Central U. S. regions. This variety has been tested in Wisconsin and Illinois and is intended for use in the North Central and East Central U. S. regions.

Reaction to pea aphid, blue alfalfa aphid 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 1996. 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.
