Objective:
To evaluate spring wheat varieties and experimental lines for agronomic performance in environments and cropping systems representative of northwestern Montana
Personnel:
Clint Beiermann, Jason Cook, Hwa-Young Heo, Jessica Pavelka
Summary:
One hundred and twenty-one spring wheat lines were planted on April 27th, 2022 and managed under rainfed conditions (Table 1). A total of 8.9 inches of rainfall was received during the growing period (April-September).
Average spring wheat yield was 79.1 bu/A and ranged from 98.6 bu/A for MT 21272to 59.1 bu/A for MT 21359. The protein content averaged 10.5% for the study. The highest protein content was 11.8% for MT 21439, while the lowest was 9.3% for MT 21286. The average heading date was 185 julian days, with the earliest at 181 for MT 21215 to the latest at 188 for MT 21288. The average test weight was 63.6 lb/bu, with the highest at 65.2 lb/bu from MT 21297 and the lowest at 62.0 lb/bu from MT 21430.
