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 predominantly, 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, pea aphid and potato leafhopper yellowing and moderate resistance to anthracnose and stem nematode. Reaction to blue alfalfa aphid and spotted alfalfa aphid has not been determined.
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.
