The USDA-coordinated hard red spring wheat uniform regional scab nursery (URSN) was initiated in 1995 in response to the emerging threat posed by Fusarium head blight in US spring wheat growing regions. 2024 marked the 30th consecutive year of testing breeding material in these artificially inoculated nurseries. Here I will describe how the number and location of testing sites, data collected, number of entries screened, as well as number and type of participants has evolved over the URSN's history. All URSN data is deposited in the T3 database and is publicly available on the GrainGenes website. These data represent a valuable resource and have been accessed by USDA and academic collaborators to develop a genomic prediction model to aid in the advancement of experimental lines in breeding programs. We invite industry, academic, and government cooperators to submit seed for testing and look forward to continuing to provide valuable scab related data to our stakeholders.
