Summary:

Spring Wheat was seeded on April 21, 2021 and managed under rainfed conditions (Table 1).  A total of 8.9 inches of rainfall was received during the growing period (April-Aug).

The highest yielding variety was MT 2013 with an average yield of 125.0 bu/A. The lowest yielding variety was SYN 213 with an average yield of 77.9 bu/A. The overall yield average was 97.5 bu/A. The average protein content was 11%. There was a three way tie for the highest protein percentage at 12.7% between MT 2013, SYN 211, and MT 2049. The lowest protein was MT 2034 at 9.5%. The average test weight was 59.6 lb/bu and ranged from 62.6 lb/bu for WB 173 to 56.6 lb/bu for BZ917-252. While 43 varieties showed no signs of lodging, 21 varieties ranged from slight to very substantial lodging. The highest lodged variety was CI 10003 at 71.7% (Table 2).
