DAGGER+EV
1. Dagger +EV is a 44 clone synthetic cultivar. Parent clones trace to 17 populations selected for resistance to the following pests: bacterial wilt, Fusarium wilt, Verticillium wilt, Phytophthora root rot, anthracnose (race 1), stem nematode, root lesion nematode and Aphanomyces root rot (race 1) plus two additional isolates. Phenotypic recurrent selection was used. Final selections were made from two-year old space plant selection nurseries near Lamed, Kansas, based on yield, winter survival, degree of leaf hopper yellowing and stunting, freedom from leaf diseases and fall dormancy reaction.
Breeder seed (syn1) was produced in 1996 on approximately 25 cuttings of each clone transplanted at random and harvested in bulk.
Parentage traces to Arrow 21 %, Apollo II, Apollo Supreme and Envy (15% each) Garst 645, AP 8922, Endure, Answer, Atlas, Trident, Saranac AF, Impact and Olympic (3% each) with 7% from numerous other sources.
2. Dagger +EV appears to be adapted to the Great Plains and east central regions of the U.S. It is intended for use in the Great Plains and east central regions of the U.S. It has been tested in Kansas, Iowa, Illinois, Idaho, and Pennsylvania.
3. Fall dormancy of Dagger +EV is similar to Archer the Fl) 5 check. Flower color of syn.2 generation is approximately 74% purple and 26% variegated with a trace of cream, yellow and white.
4. Dagger +EV has high resistance to bacterial wilt, Verticillium wilt, Fusarium wilt, anthracnose (race 1), Phytophthora root rot, pea aphid and Aphanomyces; root rot (race 1), resistance to stem nematode and root lesion nematode, moderate resistance to blue alfalfa aphid, spotted alfalfa aphid and low resistance to northern root knot nematode.
5. Seed increase is limited to one generation each of breeder (synl), 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 producing breeder, foundation and certified seed classes respectively. Foundation seed production is limited to the Pacific Northwest. Breeder seed was produced in 1996. ABI will maintain sufficient seed stocks for the life of the variety.
6. Certified seed will be available in 1999.
7. Application will not be made for Plant Variety Protection.
