Interpretive Summary:

Technical Abstract: The Uniform Regional Scab Nursery for Spring Wheat Parents (URSN) was grown for the 21st year in 2016. Five locations (Brookings, SD, St. Paul and Crookston, MN, Prosper, ND, and Morden, Canada) reported results. A total of 33 entries was included in the 2016 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 five university and two industry wheat breeding programs. A core set of traits evaluated at the nursery locations 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 two or more locations. Additional agronomic trait data are presented in individual location summary tables for locations where they were measured. Overall means for traits over locations are presented, as are relative rankings for incidence, severity, disease index, and VSK. Correlation coefficients are provided between incidence, severity, disease index, and VSK. Molecular marker genotypes for a set of FHB resistance QTLs and other traits are provided for entries. Adult plant leaf and stem rust reactions are also presented.
