Available: http://wheat.pw.usda.gov/GG2/index.shtml. Technical Abstract: The Hard Red Spring Wheat Uniform Regional Nursery (HRSWURN) was planted for the 76th year in 2004. The nursery contained 35 entries submitted by 8 different scientific or industry organizations, and 5 checks. Trials were conducted as randomized complete blocks with three replicates. The HRSWURN was planted at 20 locations in 7 different States in the U.S.A. (MN, ND, SD, MT, NE, WY, and WA), and two Canadian Provinces (Manitoba and Saskatchewan). Seventeen locations provided data for inclusion 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 as well, and yield rankings for individual locations are provided. Two-year means for entries previously entered in the 2003 HRSWURN are presented separately. Entries were also evaluated for Fusarium head blight resistance in scab nurseries at St. Paul and Crookston, MN, and at Prosper, ND. Seedling leaf rust resistance was evaluated in St. Paul, MN. These data are presented individually. The highest average yielding location was Powell, WY, with 122.1 Bu/Ac, while the lowest yielding location was Hettinger, ND, with 48.9 Bu/Ac. The average yield for the 19 combined locations was 68 Bu/Ac.
