Interpretive Summary: Every year USDA-ARS in St. Paul MN coordinates testing of spring wheat breeding lines from State Agricultural Experiment Stations in South Dakota, North Dakota, Minnesota and Montana. In 2021, 22 lines were tested for yield and other agronomic traits in replicated trials at 14 locations in four states. The wheat breeding lines are also tested for resistance to important diseases such leaf rust and stem rust, at the USDA-ARS Cereal Disease Laboratory, and for Fusarium head blight at the University of Minnesota. The wheat breeding lines were also tested for the presence of DNA markers that are linked to agronomic traits and disease resistance genes by the USDA-ARS in Fargo ND. The yield data from the individual locations are presented as well the average yields across all locations. The results are communicated directly to the cooperating wheat improvement programs, which use the results to select lines for release as wheat cultivars in the northern spring wheat region of the U.S.

Technical Abstract: The Hard Red Spring Wheat Uniform Regional Nursery (HRSWURN) was planted for the 91st year in 2021. The nursery contained 22 entries submitted by 5 different scientific or industry breeding programs, and 6 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), two locations were dropped due to extreme drought. 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 15, and yield rankings for individual locations are found in Table 16. 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 17 and 18. Entries were evaluated for Fusarium head blight resistance at St. Paul and Crookston, MN; these results are provided in Tables 19 and 20, respectively. Molecular marker genotyping for select agronomic, quality and disease resistance traits was also performed; this information is presented in Table 21. The highest average yielding location was Casselton, ND, with 100.7 Bu/Ac, while the lowest yielding location was Williston, ND, with 15.9 Bu/Ac.
