Interpretive Summary:

Technical Abstract: The Hard Red Spring Wheat Uniform Regional Nursery (HRSWURN) was planted for the 90th year in 2020. The nursery contained 23 entries submitted by 5 different scientific or industry breeding programs, and 5 checks (Table 1). Trials were conducted as randomized complete blocks with three replicates except where noted. The HRSWURN was planted at 14 locations in 4 different states in the USA (MN, ND, SD, MT). All locations provided data included in this report (Figure 1, Table 2). Data summaries for each of the reporting locations are presented in individual tables. Overall means across locations for a set of core traits are summarized in Table 17, and yield rankings for individual locations are found in Table 18. Entries were also evaluated for various diseases at different locations; these can be found by looking at individual location data summaries. Leaf rust and stem rust resistance was evaluated in St. Paul, MN. These results are presented in Tables 19 and 20. Entries were evaluated for Fusarium head blight resistance at St. Paul and Crookston, MN; these results are provided in Tables 21 and 22, respectively. Molecular marker genotyping for select agronomic, quality and disease resistance traits was also performed; this information is presented in Table 23. The highest average yielding location was Bozeman, MT, with 86.1 Bu/Ac, while the lowest yielding location was Hettinger, ND, with 27.3 Bu/Ac.
