Objective:

To evaluate the performance of selected winter wheat varieties in production environment in northwestern Montana.

Personnel:

David Larson, Jessica Pavelka, Clint Beiermann, Jessica Torrion, Suchismita Mondal

Summary:

There were 49 varieties planted 3 October 2022, and harvested on 14 August 2023, cultural practices can be found in Table 1. The 49 varieties were rainfed, receiving 10.5 inches between planting and harvest.

Average yield was 142.5 Bu/A with LCS Eclipse AX having the highest (170.2 Bu/A) and WB4727 being the lowest (109.3 Bu/A).  Average protein was 11% with Warhorse having the highest (12.43%) and LCS Steel AX the lowest (9.63%). Average number of days to heading was 155.2 days with MTS1908 having the longest time (159 days) and CP7909 the shortest period (150 days). Average period to physiological maturity was 201 days, with ACC Wildfire and LCS Steel AX having the longest time to physiological maturity (205 days) and Fortify SF and SY Wolverine having the shortest, (198 days).
