Objective:
To evaluate the performance of selected spring wheat varieties in production environment in northwestern Montana.
Personnel:
David Larson, Jessica Pavelka, Jason Cook, Hwa-Young Heo, Jessica Torrion
Summary:
The spring wheat advanced trial of 64 entries was seeded on 26 April 2023 and harvested on 30 August 2023. Detailed cultural practices are provided in Table 1. This was a rainfed trial and received 5.68 inches of rainfall for the growing season.
Average yield was 110.9 Bu/A with AGRIPR 141 having the best performance with (127.1 Bu/A) and WB222 the lowest (90.5 Bu/A). Average heading date was day 169 (June 18th) with MT 21074 having the earliest (day 166; June 15th) and LIMAGR 222 the latest (day 175; June 24th) Average thousand kernel weight was 41.3g with MT21325 being the highest (49.3g) and BZ 996434 being the smallest (32.9g). Average protein was 12.3%, with SYN 222 the highest (13.8%) and SYN 183 the lowest (11%). Average test weight was 61.6 lbs./Bu, PI 679964 was the highest (64.3 lbs./Bu) and WB 211 the lowest (59.8 lbs./Bu).
