Objective:                   To evaluate the performance of developmental spring wheat lines in northwestern Montana

Personnel:                  Clint Beiermann, Jason Cook, Hwa-Young Heo, Jessica Pavelka

Summary:

Spring Wheat was seeded on April 27th, 2022 and managed under rainfed conditions (Table 1).  A total of 8.8 inches of rainfall was received during the growing period (April-August).

The highest yielding variety was LCS HammerAX with an average yield of 106.7 bu/A. The lowest yielding variety was THATCHER with an average yield of 55.4 bu/A. The overall yield average was 78.4 bu/A. The average protein content was 10.7%. The highest protein content was 11.6% from MT 21091 and the lowest was 9.7% for MT 2063. The average test weight was 63.3 lb/bu and ranged from 65.6 lb/bu for WB 9719 to 61.6 lb/bu for MT 2049. The average heading date was 185 julian with the earliest heading date at 183 julian for eighteen of the varieties, to the latest at 189 julian from NS PRESSER CLP.
