Technical Abstract: The Hard Red Spring Wheat Uniform Regional Nursery (HRSWURN) was planted for the 79th year in 2007. The nursery contained 36 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 19 locations in 6 different States in the USA (MN, ND, SD, MT, WY, and WA), and two Canadian Provinces (Manitoba and Saskatchewan). Eighteen 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 and yield rankings are summarized, and 2-year means for entries entered previously in the 2006 HRSWURN are presented. Entries were also evaluated for various diseases at different locations; these can be found by looking at individual location data summaries. Seedling leaf rust resistance was evaluated in St. Paul, MN, stripe rust evaluations were run in fields near Pullman, WA, and entries were evaluated in a Fusarium head blight nursery at Crookston, MN. The highest average yielding location was Powell, WY, with 94.7 Bu/Ac, while the lowest yielding location was Winnipeg, Canada, with 25.4 Bu/Ac. The average yield for 17 combined locations where the nursery was replicated was 50 Bu/Ac.
