Final selections were based on yield, winter survival, degree of leafhopper yellowing, freedom from leaf disease and fall dormancy reaction.

4. Abilene +Z has high resistance to bacterial wilt, Verticillium wilt, Fusarium wilt, anthracnose (race 1), Phytophthora. root rot and pea aphid, resistance to Aphanomyces; rootas rot (race 1), stem nematode and root lesion nematode and moderate resistance to spotted alfalfa aphid and blue alfalfa aphid. It has not been tested for reaction to root knot nematode.
5. Seed increase is limited to one generation each of breeder (syn1), foundation (syn2) and certified (syn3) seed classes. Certified seed may be produced from either breeder or foundation classes. A one, three and six year stand life is permitted on fields producingbreeder, foundation and certified seed classes respectively. Foundation seed production is limited to the Pacific Northwest. Breeder seed was produced in 1997. ABI will maintain sufficient seed stocks for the life of the variety.
6. Certified seed will be available in 2000.
7. Application will not be made for Plant Variety Protection.
