Interpretive Summary:

Technical Abstract: Cooperative Regional Performance data are presented and summarized for entries in the 1994 Uniform Midseason Oat Performance Nursery. The entries included 36 experimental lines from ten public oat breeding programs plus four long term check cultivars. The nursery was grown at 26 locations in 12 states and two Canadian provinces. 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 104.6 bushels per acre in 1994 was 4.0 percent above the nursery mean yield of 100.6 bushels per acre in 1993 and 7.9 percent below the nursery mean yield of 113.6 bushels per acre in 1992. The cool, moist weather during the summer of 1994 was favorable for crown rust disease development at two locations, producing severe 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 weight, groat percentage, protein, beta-glucan 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.
