AmeriStand 403T
1. AmeriStand 403T was selected for tolerance to continuous grazing (two cycles of recurrent phenotypic selection) by cattle while maintaining a healthy, large crown and root system.
2. AmeriStand 403T 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. as a grazing crop as well as for producing stored feed. It has been tested in Iowa, Wisconsin and Illinois.
3. The fall dormancy of AmeriStand 403T is similar to the FD 4 check Saranac. Winter survival is similar to the WS2 check Vernal. Flower color of syn 2 generation is approximately 69% purple and 31% variegated with a trace of white, cream and yellow. Tolerance to continuous grazing is superior to Alfagraze.
4. AmeriStand 403T has high resistance to bacterial wilt, Verticillium wilt, Fusarium wilt, Phytophthora root rot, anthracnose (race 1), Aphanomyces root rot (race 1), resistance to Aphanomyces (race 2) and pea aphid, moderate resistance to spotted alfalfa aphid and stem nematode. It has not been tested for reaction to blue alfalfa aphid and root knot nematode.
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 1, 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 1998. ABI will maintain sufficient seed stocks for the life of the variety.
6. Certified seed will be available in 2001.
7. Plant Variety Protection will not be applied for.
