Summary:

64 entries of spring wheat, in three repetitions, were planted on 28 April 2025 and harvested on 25 September 2025.  Detailed cultural practices are provided in Table 1. This was a rainfed trial and received 6.62 inches of rainfall for the growing season.

Mean yield was 126 Bu/A with WF 241 having the highest (154 Bu/A) and CI 10003 the lowest (83 Bu/A). Mean test weight was 63 Lbs./Bu, with SYN 241 the highest (65 Lbs./Bu) and CI 10003 the lowest (61 Lbs./Bu). Mean protein was 14.89%, with MT 23085 the highest (16%) and WF 241 the lowest (13%). Mean heading date was day 174 (23 June) with MT 23130 having the earliest (day 169; 18 June) and WF 242 the latest (day 192; 10 July). Mean grain fill was 42 days with MT 21484 the longest (47 days) and WF 242 the shortest (33 days). Mean falling number was 372 seconds, with PI 574642 was the highest (492 seconds) and WF 242 the lowest (179 seconds).
