1. The parent clones were selected from approximately 200 clones screened for bacterial wilt resistance in the greenhouse from a large number of selections obtained from old alfalfa fields (over 25 years old) in Wyoming by G.H. Starr in 1938-39. Progeny evaluations were made in polycross and diallel tests.
2. Tested in Wyoming, Nebraska, Iowa, Illinois, Indiana, Minnesota and Wisconsin. Probable area of adaptation - Wyoming, western Nebraska and areas with similar climatic conditions for hay.
3. Approximately 80% purple flowers, 20% blue-green, erect growth, resistant to bacterial wilt. Winter hardiness is similar to that of Ranger.
4. Twenty-five pounds of breeder seed are on hand. This will be planted in 1967 to produce foundation seed. Certified seed will be produced from foundation seed. Seed generations beyond certified will not be called Fremont. The Wyoming Agricultural Experiment Station will maintain the parent clones and produce the breeder seed. An equal number of plants of each clone will be placed in each crossing block in a manner to give each clone equal opportunity to be cross-pollinated with other clones in the block. The crossing will be accomplished either under field isolation or under cage. Seed from clones will be bulk harvested. The original breeder seed was produced in an isolated crossing block, with 30 plants of each clone per row and replicated 10 times in such a manner that each of the clones was grown along side of every other clone approximately 5 times. The plot was bulk harvested.
5. 1968 or 1969.
