Root 66
1. Root 66 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. Root 66 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 Root 66 is similar to the FD 4 check Saranac. Flower color of syn 2 generation is approximately 71% purple and 29% variegated with a trace of white, cream and yellow. Tolerance to continuous grazing is superior to Alfagraze.
4. Root 66 has high resistance to bacterial wilt, Verticillium wilt, Fusarium wilt, Phytophthora root rot, Aphanomyces root rot (race 1), and anthracnose (race 1) and resistance to 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 (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 1997. 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.
