Interpretive Summary: The Uniform Winter Barley Yield Nursery (UWBYN) is a cooperative effort of the USDA-ARS and various state Agricultural Experiment Stations to allow plant breeders to evaluate promising experimental cultivars for their agronomic performance in a wide variety of growing conditions. The choice of experimental design used to grow the nursery was made by the cooperator for each location and average performance values were submitted for inclusion in this report. Data reported from various stations included yield, test weight, head date, plant height, lodging, winter kill, powdery mildew, BYDV, leaf rust, spring stand, fall stand, and vernalization response. The combined Central and Southern Uniform Winter Barley Yield Nursery was grown at 12 stations in 8 states. There were 23 entries including 10 that were new in 2001-02 Nursery. The average yield over all lines and stations was 76.3 bu/A with line averages ranging from 49.6 to 130.2 bu/A. VA97B-176 was the top yielding experimental line, with 5 other lines yielding at levels that were not statistically different from this line, when averaged over all locations. The highest yielding location was Warsaw, VA. where the average of all entries was 130.2 bu/A. The best entry for test weight, when averaged over all locations, was Perkins at 47.7 lb/bu. Two other lines had average test weights that were not statistically different from this line.
