Technical Abstract: The Uniform Regional Scab Nursery for Spring Wheat Parents (URSN) was grown for the 15th year in 2009. Five mist-irrigated locations at Brookings, SD; St. Paul, and Crookston, MN; Langdon, ND; and Glenlea, Manitoba, Canada, were planted. A total of 33 entries were included in the 2009 URSN, including the resistant checks 2375, BacUp, and ND2710, and the susceptible checks Wheaton and Oslo. The other entries were contributed by seven university and industry breeding programs. A core set of traits evaluated provided from most locations included scab incidence, scab severity, disease index (incidence x severity), and visual scabby kernel ratings (VSK, tombstone, FDK). Additional recorded trait data such as grain deoxynivalenol content, plot yield, and heading date are presented on a location by location basis. Means for traits over locations are presented as are relative rankings for scab incidence, severity, disease index, and VSK. Correlation coefficients are provided between scab incidence and severity, disease index, and VSK. Further, molecular marker genotypes for FHB resistance QTLs and 13 other traits are provided for entries.
