Available: http://wheat.pw.usda.gov/GG2/index.shtml. Technical Abstract: The Hard Red Spring Wheat Uniform Regional Nursery (HRSWURN) was planted for the 78th year in 2006. The nursery contained 35 entries submitted by 12 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 21 locations in 7 different states in the USA (MN, ND, SD, MT, NE, WY, and WA), and two Canadian provinces (Manitoba and Saskatchewan). Twenty 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, and yield rankings for individual locations are also reported. Entries were evaluated for various diseases at different locations. Seedling leaf rust resistance was evaluated in St. Paul, MN, and stripe rust evaluations were run in fields near Pullman, WA. Lastly, entries were evaluated in a Fusarium head blight nursery at Crookston, MN. The highest average yielding location was Winnipeg, Canada, with 79.2 Bu/Ac, while the lowest yielding location was Williston, ND, with 31.2 Bu/Ac. The average yield for 19 combined locations where the nursery was replicated was 58.1 Bu/Ac.
