Interpretive Summary:

Technical Abstract: The Uniform Regional Scab Nursery for Spring Wheat Parents (URSN) was grown for the 25th year in 2020. Six locations (Brookings, SD, St. Paul, MN, Crookston, MN, Prosper, ND, Langdon, ND, Fargo, ND) reported results. A total of 23 entries was included in the 2020 URSN, in addition to the resistant checks 2710, BacUp, and Rollag, the susceptible checks Wheaton, Oslo, and Norm, and N10, a Norm near-isoline containing Fhb1. The entries were contributed by four university wheat breeding programs. The core set of traits evaluated at the nursery locations varied, but most included Fusarium head blight (FHB) incidence, FHB severity, and disease index. In addition, visual scabby kernel ratings (VSK/tombstone/FDK) were provided for locations. Additional agronomic trait data are presented in individual location summary tables for locations where they were measured. Adult plant leaf and stem rust reactions, as well as seedling stem rust reactions, are also presented. Molecular marker genotypes for a set of FHB resistance QTLs and other traits are provided for entries.
