AS-49
1. Seed was collected from 12 plants growing in source nurseries in California and Arizona. Six of the plants trace to the variety Cody, three to Zia, and three to Lahontan. The plants were chosen because of their seed production ability, spotted alfalfa aphid resistance, and general agronomic traits. From each of the 12 seed lots, 36 seedlings were selected, based upon seedling vigor. These 432 seedlings were placed at random in an isolation-crossing block and used as a source of breeder seed.
2. Sold in southwestern United States for hay, greenchop, and de-hy operations. It is well adapted to central and northern regions of California. Tested in Arizona, San Joaquin and Sacramento Valleys in California.
3. Predominantly purple flowers, fairly uniform growth, and semi-dormant winter growth habit in California. Growth habit is upright. Resistant to spotted alfalfa aphid.
4. Seed production of AS-49 shall be on a four-generation basis: breeder, foundation, registered, and certified. Stock seed (breeder, foundation and registered classes) will be produced in California. A reserve of breeder seed harvested in 1960-1961 from original 432 plants is maintained by Farm Seed Research Corporation. Breeder seed will only be released to Ferry-Morse Seed Company for production of foundation seed. Foundation seed will be used to produce registered or certified seed. Certified fields will be established with registered or foundation seed.
