Objective:
To evaluate the performance of selected winter wheat varieties in a production environment in northwestern Montana
Personnel:
Clint Beiermann, Suchismita Mondal, Jacob Tracy, Jessica Pavelka
Summary:
The winter wheat intrastate trial was planted on September 24th, 2021 (Table 1) with 49 varieties and managed with supplemental overhead sprinkler irrigation.
The average yield for the study was 126.7 bu/A. The lowest yield was 91.9 bu/A for CP7909 while the highest yield came from LCS Helix AX at 149.0 bu/A which also had one of the lowest protein contents at 11.0%. The average protein was 12.0% and the highest protein content was up to 13.4% for CP7050AX. Winter survival ratings ranged from 99% to 77.3%, forty-two of the varieties were statistically equal to the highest value based on Fischer’s LSD(α = 0.05), while seven of the varieties were statistically different. The average heading date was 160 julian days, with the earliest date being 154 julian days from CP7909 to the latest date at 166 julian days from MT WarCat (Table 2).
