Technical Abstract: The Uniform Regional Scab Nursery for Spring Wheat Parents (URSN) was grown for the 18th year in 2013. Three locations (Brookings, SD, and St. Paul and Crookston, MN) were planted. A total of 23 entries were included in the 2013 URSN, in addition the resistant checks 2375, BacUp, and ND2710, and the susceptible checks Wheaton and Oslo. The entries were contributed by 5 university and industry breeding programs. A core set of traits evaluated provided from locations included Fusarium head blight (FHB) incidence, FHB severity, disease index (incidence x severity), and visual scabby kernel ratings (VSK, tombstone). Additional trait data such as grain deoxynivalenol content, yield and heading date, are presented in individual location summary tables where they were measured. Overall means for traits over locations are presented, as are relative rankings for incidence, severity, disease index, VSK and DON. 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.
