Technical Abstract: The Hard Red Spring Wheat Uniform Regional Nursery (HRSWURN) was planted for the 74th year in 2002. The nursery contained 32 entries submitted by 10 different scientific or industry organizations, and 5 checks. Trials were conducted as randomized complete blocks with three replicates. The HRSWURN was planted at 19 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). All but one of the locations provided data for analysis and inclusion in this report. Data recorded at each of these locations are presented individually in the report. For each location, entries are presented in their order of yield. Overall means across locations for a set of traits are summarized, as are 2-year means for entries previously entered in the 2001 HRSWURN. The highest average yielding location was Bozeman, MT, with 60 Bu/Ac, while the lowest yielding location was Hettinger, ND, with approximately 20.6 Bu/Ac. The average yield for the 16 combined locations was 39.8 Bu/Ac. Sixteen lines fell within 1/2 of one LSD unit of this value, and 26 fell within 1 LSD unit. The five top yielding lines were SD3641, ND744, SD3623, N99-0107, and N98-0286, which each exhibited mean yields exceeding 43 Bu/Ac. The entries with the highest test weights were 01M96, MN97695-4, FA-900-720, ND744, and ND739. Combined data for experimental lines and checks grown in both the 2001 and 2002 HRSWURN indicate that the highest yielding entries across these years were SD3540, SD3546, and ND741. The highest test weight entry was FA-900-720 (61 Lb/Bu), followed by SD3546 and ND741. The entries were also evaluated for Fusarium head blight resistance in nurseries at St. Paul and Crookston, MN, and at Langdon, ND. Adult plant leaf and stem rust resistance of entries was evaluated in three North Dakota nurseries and one nursery in St. Paul, MN. Seedling stem rust resistance was evaluated as well. These disease resistance data are summarized in the report.
