Technical Abstract: The Uniform Regional Scab Nursery for Spring Wheat Parents (URSN) was grown for the 16th year in 2010. Five mist-irrigated locations at Brookings, SD, St. Paul and Crookston, MN, Langdon, ND, and Glenlea, Manitoba, Canada, were planted. A total of 37 entries were included in the 2010 URSN, including the resistant checks 2375, BacUp, and ND2710, and the susceptible checks Wheaton and Oslo. The other entries were contributed by seven university, government, and industry breeding programs. A core set of traits evaluated provided from most locations included Fusarium head blight (FHB) incidence, FHB severity, disease index (incidence x severity), and visual scabby kernel (VSK) ratings (VSK approximately equal to tombstone approximately equal to Fusarium damaged kernels (FDK)). Additional trait data such as grain deoxynivalenol (DON) content, plot yield, and heading date, are presented in individual location summary tables. 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. Further, molecular marker genotypes for a set of FHB resistance QTLs and 13 other traits are provided for entries.
