Technical Abstract: The Hard Red Spring Wheat Uniform Regional Nursery (HRSWURN) was planted for the 80th year in 2008. The nursery contained 37 entries submitted by 13 different scientific or industry breeding programs, and 5 checks. Trials were conducted as randomized complete blocks with three replicates except where noted. The HRSWURN was planted at 18 locations in 6 different States in the U.S. (MN, ND, SD, MT, WY, and WA), and two Canadian Provinces (Manitoba and Saskatchewan). Sixteen locations provided data included in this report. Data summaries for each of these locations are presented. For each location summary, entries are listed in descending order of yield. Overall means across locations for a set of core traits are summarized, and yield rankings for individual locations are also reported. Two-year means for entries entered previously in the 2007 HRSWURN are presented. Entries were also evaluated for various diseases at different locations. Seedling and adult plant leaf rust resistance was evaluated in St. Paul, MN, and stripe rust evaluations were completed at three field locations in WA. Lastly, entries were evaluated in Fusarium head blight nurseries at Crookston and St. Paul, MN. The highest average yielding location was Powell, WY, with 106.1 Bu/Ac, while the lowest yielding location was Williston, ND, with 31.1 Bu/Ac. The average yield for 16 combined locations where the nursery was grown in replicated trials was 63.6 Bu/Ac.
