NURSERY DESCRIPTION AND SUMMARY 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 or industry organizations, and 5 checks (Table 1). 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). All but two of the 18 total locations were harvested (Table 2). Data recorded at each of these 16 locations are presented in Tables 3 through 18. For each location, entries are presented in their order of yield. Overall means across locations for a set of traits are summarized in Table 19. 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 (Sidney, NE, Swift Current, CAN, and St. Paul, MN were excluded due to high cv's, Morris, MN did not report yield) 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 are provided in Table 20. The highest yields were observed in SD3367, MN97803, and SD3496. The highest test weight entry 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. These data are recorded in Tables 21 and 22 (FHB) and 23 and 24 (leaf and stem rust, respectively).
