Bonanza
1. Clones were selected for vigorous fall growth and potato leafhopper resistance from non-hardy, spotted aphid resistant lines. Clones with fungus diseases were avoided. Replicated clonal nurseries containing the same clones were established at Lafayette, Indiana, and Westley, California. Selection of the 35 parent clones was based on the performance of the clones at both locations plus single cross and polycross progeny tests at Lafayette.
2. Bonanza will be grown for hay production in California and as a one-year alfalfa in the Corn Belt. In actual hay fields, evaluation has been limited to 1965 and 1966 crop years in California but seed production fields have been harvested for three years without stand problems. In the Corn Belt, seedling year yield tests have been conducted in Indiana and Ohio plus observational plantings in Wisconsin and Minnesota.
3. Flower color, growth habit, and leaf color are relatively uniform. Non-dormant and upright. Flowers are purple. Resistant to downy mildew.
4. Parental clones will be maintained by F.F.R., Lafayette, Indiana. Breeder seed will be the interpollinated, bulk harvested seed from an isolated planting made from vegetative cuttings of the 35 parental clones. Foundation seed will be the first generation seed grown from breeder seed in California. Certified seed will be produced from either breeder or foundation seed. In no instance will seed grown from other than foundation or breeder seed be considered Bonanza by F.F.R.
