Technical Abstract: The Hard Red Spring Wheat Uniform Regional Nursery (HRSWURN) was planted for the 73rd year in 2001. The nursery contained 27 entries submitted by 8 different scientific and industry organizations, and 5 check varieties. Trials were conducted as randomized complete blocks with three replicates. The HRSWURN was planted at 16 locations in 7 different states in the USA (MN, ND, SD, MT, NE, WY, and WA), and at two locations in separate provinces in Canada (Manitoba and Saskatchewan). The highest average yielding location was Bozeman, MT with 78 Bu/Ac, while the lowest yielding location was Sidney, NE with approximately 17 Bu/Ac. The average yield combined across 12 locations was 56.9 Bu/Ac. Fifteen lines fell within 1/2 of one LSD unit of this value, and 27 fell within 1 LSD unit. The five top yielding lines were ND740, N97-0100, FA900-720, SD3546, and SD3540, which each exhibited mean yields exceeding 60 Bu/Ac. The entries with the highest test weights were FA900-720, ND729, ND740, SD3506, and SD3546. Combined data for experimental lines and checks grown in both the 2000 and 2001 HRSWURN revealed the highest yields in SD3367, MN97803, and SD3496. The highest test weight entry for the combined 2000-2001 years was ND729 (61 Lb/Bu), followed by SD3506 and MN97448. The entries were also evaluated for Fusarium head blight resistance in scab nurseries at St. Paul and Crookston, MN, and for both leaf and stem rust resistance in three North Dakota rust nurseries to provide additional information on this germplasm for the breeding community.
