Interpretive Summary:

Technical Abstract: Cooperative Regional Performance data are presented and summarized for entries in the 1994 Uniform Early Oat Performance Nursery. The entries included 34 elite experimental lines from nine public oat breeding programs plus five long term check cultivars. The nursery was grown at 14 locations in 14 states. Evaluation of performance of elite experimental lines across the wide range of environments aids the cooperators to identify potential cultivar releases and germplasm for use in new crosses. The nursery mean yield of 104.5 bushels per acre in 1994 was 20.5 percent above the 87.0 bushels per acre in 1993 and 7.0 percent below the record nursery mean yield of 112.4 bushels per acre in 1992. Crown rust disease development was severe at Rosemount, Minnesota, producing large reductions in yield and seed quality in all but the few entries with adequate genetic resistance. Multiple location data are presented for seed quality traits including test tweight, groat percentage, protein, and oil contents, for several disease reactions including rusts, smut and barley yellow dwarf virus, and for various other agronomic traits, including maturity and lodging resistance.
