Objective:

To evaluate the performance of selected winter wheat in northwestern Montana

Summary:

Forty-nine (49) winter wheat varieties/lines were planted in fall 2019, and managed under rainfed condition (Table 1). A total of 16.5 inches rainfall was received during the growing period (Sept. 2019 -Aug. 2020).

On average, the grain yield was 153 bu/a, and ranging from 122 bu/a for SY 517 CL2 to 173.5 bu/a for WB4792. Grain test weight (TWT) averaged 62.2 lbs/bu, ranging from 58.6 lbs/bu for MTS18149 to 64.8 lbs/bu for SY 517 CL2 (Table 2). The average day for heading was 166 with the earliest heading at 156 for CP7909 and the latest was at 171 for both Loma and MTS1831. The average plant height was 37.2 inches. The tallest variety was AAC Wildfire and the shortest was SY 517 CL2. Thousand kernel weight (TKW) averaged 43.5 g, ranging from 35.6.8 g for WB4418 to 56.5 g for Mpress (SWW). Falling no. averaged 326 sec., and ranging from 258.5 sec. for Loma to 426.4 sec. for MT1848. Average grain protein content was 10.2%; Brawl CL Plus had the highest protein content at 11.4%, whereas Incline AX had the lowest protein content at 8.9%.
