Interpretive Summary:

Technical Abstract: The Uniform Regional Scab Nursery for Spring Wheat Parents (URSN) was grown for the 14th year in 2008. Five mist-irrigated locations at Brookings, SD; St. Paul, and Crookston, MN; Langdon, ND; and Glenlea, Manitoba, Canada, were planted. A total of 36 entries were included in the 2008 URSN, including the resistant checks 2375, BacUp, and ND2710, and the susceptible checks Wheaton and Oslo. Rugby was included as a durum check. The other entries were contributed by eight university and industry breeding programs. Three of these entries were durum wheat and the rest were hard red spring wheat. 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, Fusarium damaged kernels (FDK)). Additional recorded trait data such as grain deoxynivalenol content, plot yield, and heading date, are presented in individual location summary tables. Overall means for traits across 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.
