Interpretive Summary: Each year new lines from public and private spring wheat breeders are tested at 22 locations in the USA and Canada. The USDA-ARS has been conducting these uniform nurseries for 66 years in the spring wheat region. The multiple environment tests provide the researcher with information as to how cultivars will react to a wide range of environmental conditions. Line stability across these environments provides information as to the future performance of these materials. The Uniform Regional Nursery allows evaluation of future varieties and, with the developers' permission, use of the lines as parents. This free exchange of germplasm is the highest form of cooperation among plant breeders. The Uniform Regional Nursery also provides bread making quality information about the potential varieties performance. Millers and bakers have sufficient interest in this nursery to request a report each year at the annual Spring Wheat Quality Council meeting.

Technical Abstract: The Uniform Regional Hard Red Spring Wheat Performance Nursery had 32 entries from five public wheat breeding programs, three U.S. and two Canadian, and one private company in 1994. It was grown and harvested at all 22 locations in MN, ND, SD, MT, ID, WY, WI WA, and Canada. Aberdeen, ID was the highest yielding location averaging 108 bu/A. The lowest yielding location, Tetonia, ID, averaged 27 bu/A. Highest yielding entry overall locations which had acceptable data was SBE0050 closely followed by SD0010. SBE0050 was entered by Minnesota and SD0010 was entered by South Dakota. In the four sites that were affected by scab, SBE0050 was highest yielding closely followed by SD0010, SD3151 and SD3156. Clearly, progress has been made in selecting for resistance, but scab resistance obviously is still insufficient. None of the entries had high test weight in the severe scab conditions. N90-3057 had high yield at most sites but in scab conditions was very low yielding with low test weight indicating high susceptibility.
