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

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,
