AS-67
1. AS-67 is a synthetic cultivar produced from six clones selected for vigor and persistence from five-year-old Brookings, SD evaluation plots. These six maternal clones trace to selections from Vernal (3), Ranger (2), and Montana Common (1). Pollen parents were 21 clones of Kanza and 70 clones of Dawson selected from a spotted alfalfa aphid screening trial at San Juan Bautista, CA. The Syn 1 seed was produced by handcrossing without emasculating in the greenhouse at San Juan Bautista in 1974.
2. AS-67 is adapted to the central states primarily for hay usage. It has been evaluated in Missouri, Illinois, Ohio, and South Dakota and will be marketed in the same general region.
3. Flower color is approximately 90% purples and light purples and 10% variegated with an occasional white. Persistence is similar to Vernal and fall dormancy less than Vernal.
4. AS-67 has resistance to bacterial wilt, moderate resistance to spotted alfalfa aphid and low resistance to Phytophthora root rot. Resistance to stem nematode, anthracnose, Fusarium wilt and pea aphid has not been determined.
5. Breeder (Syn 2) seed was produced on an isolation block in San Benito County, CA in 1975, 1976, and 1977. Foundation seed was produced in 1979 in Fresno County, CA. Certified seed may be produced from either breeder or foundation seed. One generation each of breeder, foundation, and certified seed classes is recognized. Foundation seed will be produced with a maximum of three harvest years on stands producing foundation seed.
6. Certified seed will be available for sale in 1980.
7. No decision has been made for plant variety protection.
