Project Title:

Winter Wheat Preliminary Yield Trial

Objective:

To test for agronomic performance of early winter wheat lines.

Personnel:

J.A. Torrion, Daniel Porter, Suchismita Mondal, Jacob Tracy

Summary:

Thirty-six winter wheat genetic lines were tested in this preliminary trial. See table 1 for the detailed management practices. Yield (bu/ac) ranged from 81.3 (MTFH2290) to 144.8 (MT2280). Protein percentage ranged from 10.8 (MTFH2292 & MT2280) to 13 (MT2278). Test weight (lb/bu) ranged from 62 (MT2278) to 65.8 (MT2286). Heading dates (Julian) ranged from 158 (MT2282) to 168 (MTFH2290). Plant height ranged from 28.4 in (MTFH2289) to 39.6 in (Yellowstone). The greatest stripe rust infection was 50.5% (Warhorse) and the rest of the lines had none to very slight infection. See table 2 for agronomic performance of all early genetic lines tested.
