1. Saranac AR was developed from one cycle of selection from U.S.D.A. germplasm GPl8 Beltsville 2--An4 (Crop Science 13:289. 1973), an anthracnose resistant population selected from Saranac. Selection was based upon one cycle of selection for vigorous plants in the field and survival in tests for resistance to the bacterial wilt and anthracnose diseases.
Breeder seed is produced from the interpollination by honey bees of 150 parent clones in a plant growth chamber.
2. Saranac AR is recommended for hay and haylage in southeastern and southern New York. The area of probable adaptation is similar to that for Saranac. It has been tested in yield trials and in demonstration trials on farms in New York. It is under test in nearby states and Eastern Canada.
3. Saranac AR is similar to Saranac for phenotypic characteristics except that it has good resistance to the causal organism for anthracnose and has slightly fewer plants with variegated flower color - approximately 14 percent for Saranac AR and 18 percent for Saranac.
4. Seed increase shall be in the limited generation sequence with one generation each of Breeder, Foundation and Certified. Production of Foundation seed will be by the New York Seed Improvement Cooperative, Inc. in the northern alfalfa region only. Certified seed fields must be planted with Breeder or Foundation seed.
5. Certified seed will be available in the Spring of 1976.
6. An application has been submitted for Plant Variety Protection under the provision that the variety may be sold by variety name only as a class of certified seed.
