Interpretive Summary:

Technical Abstract: The Uniform Regional Scab Nursery for Spring Wheat Parents (URSN) was grown for the 23rd year in 2018. Four locations (Brookings, SD, St. Paul, MN, Prosper, ND, and Morden, Canada) reported results. A total of 17 entries was included in the 2018 URSN, in addition to the resistant checks 2375, BacUp, and ND2710, the susceptible checks Wheaton, Oslo, and Norm, and N10, a Norm near-isoline containing the resistance gene Fhb1. The entries were contributed by four university wheat breeding programs. The core set of traits evaluated at the nursery locations varied, but included Fusarium head blight (FHB) incidence, FHB severity, and disease index (incidence x severity). In addition, visual scabby kernel ratings (VSK/tombstone) and grain deoxynivalenol content were provided from three or more locations. Additional agronomic trait data are presented in individual location summary tables for locations where they were measured. Molecular marker genotypes for a set of FHB resistance QTLs and other traits are provided for entries. Adult plant leaf and stem rust reactions, as well as seedling stem rust reactions, are also presented.
