Power Plant

  1. Power Plant is a 74 clone synthetic cultivar. Parent clones trace to 22 populations selected for resistance to the following pests: bacterial wilt, Fusarium wilt, Verticillium wilt, Phytophthora root rot, anthracnose (race 1) and Aphanomyces root rot (race 1) plus two additional isolates. Phenotypic recurrent selection was used. Final selections were made form two-year old space plant selection nurseries near Napier, Iowa based on yield, winter survival, degree of leafhopper yellowing and stunting, freedom from leaf diseases, fall dormancy reaction and multileaf expression.

    Breeder seed (Syn 1) was produced in 1994 on approximately 25 cuttings of each clone transplanted at random and harvested in bulk.

    Parentage traces to Stine 9227, Dawn, Aggrssor, Absolute, Venture, Garst 645 and AP 8922W 9% each and G2833, DK 122, Legend and Crown 7% each with 9% tracing to numerous breeding populations.

2. Power Plant appears to be adapted to the North Central and East Central regions of the U.S.. It is intended for use in the North Central and East Central regions of the U.S. It has been tested in Iowa, Wisconsin and Illinois.

3. Fall dormancy of Power Plant is similar to Ranger. Flower color of Syn 2 generation is approximately 73% purple and 27% variegated with a trace of cream, white and yellow. Winter survival is similar to Ranger, Multileaf expression is moderate (similar to MultiKing I).

4. Power Plant has high resistance to bacterial wilt, Fusarium wilt, and Verticillium wilt, resistance to Aphanomyces root rot (race 1) and anthracnose (race 1), and moderate resistance to pea aphid. It has not been tested for reaction to blue alfalfa aphid, spotted alfalfa aphid, stem nematode, root knot nematode, and Phytophthora root rot.

5. Seed increase is limited to one generation each of breeder (Syn 1), foundation (Syn 2) and certified (Syn 3) seed classes. Certified seed may be produced from either breeder or foundation classes. A 2, 3 and 6 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 1994. ABI will maintain sufficient seed stocks for the life of the variety.

6. Certified seed will be available in 1999.

7. Plant Variety Protection will not be applied for.
