Summary:

The off-station spring wheat trial was planted on April 22, 2020, and irrigated with 2.75 inches. See Table 1 for detailed management information.

Yields ranged from 124.8 (Corbin) to 155.9 (Duclair) bu/A, with an overall average of 142.9 bu/A (Table 2). The average test weight was 62.5 lb/bu. MT1053/MO8/3-4 had the lowest test weight whereas, SY Ingmar being the highest. The average protein content was at 14%.  The NS Presser CLP had the highest protein content (15.8%), whereas WB Gunnison and MT1274/RB07 had the lowest protein (12.9%). Fortuna was the tallest plant (45 in.), whereas both SY Soren and Brennan were the shortest (34 in.). The average falling number (FN) for this trial was 430 seconds. Both Duclair and Alum had the fastest FN (both 371 sec.). The slowest FN was the NS Presser CLP (511 sec), which also had the highest protein content amongst the cultivars tested. 

 

From seeding to harvest, this nursery received 9.7 inches of rain.
