AmeriStand 201 +Z
1. Ameristand 201+Z 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 201+Z 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 201+Z is similar to the FD 2 check Vernal. Flower color of syn.2 generation is approximately 62% purple and 38% variegated with a trace of white, 1K cream and yellow. Tolerance to continuous grazing is superior to Alfagraze.
4. AmeriStand +Z has high resistance to bacterial wilt, Verticillium. wilt, Fusarium wilt, Phytophthora root rot and Aphanomyces root rot (race 1), and resistance to anthracnose (race 1) and pea aphid. It has not been tested for reaction to stem nematode, spotted alfalfa aphid, blue alfalfa aphid and root knot nematode.
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 1997. ABI will maintain sufficient seed stocks for the life of the variety.
6. Certified seed will be available in 2000.
7. Application will not be made for Plant Variety Protection.
