Technical Abstract: The Hard Red Spring Wheat Uniform Regional Nursery (HRSWURN) was planted for the 81st year in 2009. The nursery contained 32 entries submitted by 8 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 USA (MN, ND, SD, MT, WY, and WA), and two Canadian Provinces (Manitoba and Saskatchewan). For each location summary, entries are listed in descending order of yield, overall means across locations for a set of core traits are summarized, yield rankings for individual locations are presented, and 2-year means for entries entered previously in the 2008 HRSWURN are provided. Entries were evaluated for various diseases at different locations: leaf rust resistance was evaluated in St. Paul, MN, stripe rust evaluations were completed at two field locations in WA, and entries were evaluated in Fusarium head blight nurseries at Crookston and St. Paul, MN. Molecular marker genotyping for select traits was also performed. The highest average yielding location was Powell, WY, with 114 Bu/Ac, while the lowest yielding location was Groton, SD, with 40 Bu/Ac.
