Technical Abstract: The Uniform Regional Scab Nursery for Spring Wheat Parents (URSN) was grown for the 22nd year in 2017. Six locations (Brookings, SD, St. Paul and Crookston, MN, Prosper and Langdon, ND, and Morden, Canada) reported results. A total of 20 entries was included in the 2017 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 three university and one industry 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 and tombstone) and grain deoxynivalenol content were provided from two 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.
