1. Rugged was selected for tolerance to continuous grazing by cattle (one cycle of phenotypic selection) while maintaining a large healthy crown and root system.

2. Rugged 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. Rugged is moderately dormant, similar to the FD 3 check. Winter survival is similar to the WS 2 check Vernal. Flower color of syn 2 generation is approximately 63% purple and 37% variegated with a trace of white, cream and yellow. Tolerance to continuous grazing is similar to Alfagraze.

4. Rugged has high resistance to bacterial wilt, Verticillium wilt, Fusarium wilt, Phytophthora root rot, anthracnose (race 1), Aphanomyces root rot (race 1) and pea aphid, and moderate resistance to stem nematode and Aphanomyces root rot (race 2). It has not been evaluated for resistance to blue alfalfa aphid, spotted alfalfa aphid and root knot nematode.

5. Seed increase is limited to one generation each of breeder (syn 1), foundation (syn 2) and 2 generations of certified (syn 2 or 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 1996. ABI will maintain sufficient seed stocks for the life of the variety.

6. Certified seed will be available m 2002.

7. Plant Variety Protection will not be applied for.
