Arrow
1. Arrow is a 66-clone synthetic variety. Parent clones were selected following 3 or 4 cycles of field screening for resistance to Verticillium wilt, from populations which had previously been screened for winter survival plus resistance to Phytophthora root rot, anthracnose, bacterial wilt and Fusarium wilt. Parentage traces predominately (in order of contribution) to Endure, Apollo II, Trident, WL 318, Anchor, Answer, Apollo and Saranac AR.
2. Arrow is intended for use in the northern region of the U.S. as hay, haylage, greenchop or dehy production. It has been tested in Iowa, Illinois, Wisconsin, Michigan, Pennsylvania, Kansas and Idaho.
3. Fall dormancy is similar to Ranger. Flower color of foundation generation is approximately 84% purple and 16% variegated.
4. Arrow has high resistance to Phytophthora root rot, bacterial wilt and Fusarium wilt, resistance to Verticillium wilt and potato leafhopper yellowing and moderate resistance to anthracnose. Reaction to pea aphid, spotted alfalfa aphid and stem nematode has not been adequately tested.
5. Breeder (Syn 1) seed was produced on cuttings at Nampa, Idaho, and is held in cold storage. Seed increase is limited to one generation each of breeder, foundation, and certified classes. Certified seed may be produced from either breeder or foundation seed. A 3 and 6 year stand life is permitted on fields producing foundation and certified seed respectively. Foundation seed production is limited to the northern region of adaptation.
6. Certified seed will be available in 1986.
7. Application for Plant Variety Protection has been made and the certification option was not requested.
