PAWNEE
1. Pawnee is a 85 clone synthetic cultivar. Parent clones trace to 39 populations selected for resistance to the following pests: bacterial wilt, Fusarium wilt, Verticillium wilt, Phytophthora root rot, Anthracnose (race 1), stem nematode, 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 Larned, 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 Synergy, Allegro and AP 8841 (11% each), ABI 9022, ABI 9042, ABI 9134,2444, Apollo Supreme, ZX 9345B, ABI 8939, ABI 700, SuperCuts, TW Generation and Depend +EV (5% each) with 7% from numerous other sources.
2. Pawnee 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.
3. Fall dormancy of Pawnee is similar to Archer the FD 5 check. Flower color of syn2 generation is approximately 76% purple and 24% variegated with a trace of cream, yellow and white.
4. Pawnee has high resistance to bacterial wilt, Verticillium wilt, Fusarium wilt, anthracnose (race 1) Phytophthora root rot, pea aphid and Aphanomyces; root rot (race 1), moderate resistance to spotted alfalfa aphid and stem nematode and low resistance to northern root knot nematode and blue alfalfa aphid.
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 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.
