Endure
1. Endure was developed by subjecting numerous breeding populations to two cycles of recurrent selection for Verticillium wilt resistance in the Pacific Northwest. These populations had previously been selected for winter hardiness and resistance to Phytophthora root rot, anthracnose, bacterial wilt and Fusarium wilt at Ames, Iowa. Parentage traces predominately to the varieties Atlas, Olympic, Apollo, Thunder and Armor.
2. Intended for use in the northern region of adaptation where Verticillium wilt is a problem. To be used for hay, greenchop or dehy production. Tested in Iowa, Illinois, Idaho, Michigan, Wyoming and Pennsylvania.
3. Flower color of foundation generation is approximately 82% purple, 17% variegated, and 1% green. Growth habit is erect in midsummer and semi-erect in the fall. Fall dormancy is most similar to Ranger.
4. Endure has resistance to Phytophthora root rot, bacterial wilt, Fusarium wilt and Verticillium wilt, moderate resistance to anthracnose and low resistance to spotted alfalfa aphid. Reaction to stem nematode and pea aphid has not been adequately tested.
5. Breeder (Syn 1) seed was produced on the parent plants near Nampa, Idaho, with sufficient seed for the expected life of the variety held in controlled storage. One generation each of breeder, foundation and certified classes is recognized. Certified seed may be produced from either breeder or foundation seed. A maximum of three and five years is permitted on stands producing foundation and certified seed, respectively. Foundation seed production is limited to the northern region of adaptation.
6. Certified seed will be available in 1984.
7. Application for Plant Variety Protection will be made, and the certification option will not be requested.
