Summary:

The winter wheat intrastate trial was planted on September 28th, 2020 with 49 varieties and managed under rainfed conditions (Table 1).

The average yield for the study was 122.4 bu/A. The lowest yield was 94.7 bu/A for SY 517 CL2 while the highest yield came from Yellowstone at 146.3 bu/A. The average protein was 11.7%, with the lowest protein content being 10.83% for WB4505 up to 13.56% for Brawl CL Plus. Forty varieties showed no signs of lodging, while seven only showed between 1-8% lodging. The highest lodging rate was 80% from Whistler. Winter survival ratings averaged from 98% to 91%, but were unaffected by winter wheat variety. The average heading date was 165 julian, with the earliest date being 154 julian from CP7909 to the latest date at 172 julian from MTS1831 (Table 2).
