Technical Abstract: The Uniform Regional Scab Nursery for Spring Wheat Parents (URSN) was grown for the 13th year in 2007. The nursery was planted at five mist-irrigated locations in Brookings, SD, St. Paul and Crookston, MN, Prosper, ND, and Glenlea, Manitoba, Canada. A total of 48 entries was included in the 2007 URSN, including the resistant checks 2375, BacUp, ND2710, and the susceptible checks Wheaton and Oslo. Rugby was included as a durum wheat check. The other 42 entries were contributed by 11 university, industry, and national breeding programs. Four entries were durum wheat, and the rest were hard red spring wheat. A core set of traits evaluated at 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 (DON) and heading date are presented for some locations. Overall means for traits across locations are reported 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.
