Objective:

To evaluate the agronomic performance of hull-less barley varieties grown in environment representative of northwestern Montana.

Results:

Stand establishment was poor with the majority of entries, but especially so for Franubet, Wanupana and Washonupana where the percent germination was zero. As a result these entries were dropped from the study. Plant height ranged from a high of 24.3 inches for Transit to a low of 18 inches for Falcon. Falcon also was the latest variety to head at 183 days (July 2), whereas X0626-T229 was the earliest at 176.7 days (June 25). X0626-T229 also was the highest yielding entry at 82.7 bu/A while Falcon had the lowest yield at 43.5 bu/A. Protein ranged from 15.6 % for X0626-T229 to 19 % for Transit. Test weights were low, ranging from a low of 47.9 for X07G30-T131 to 57.8 for Falcon. Percent plumps varied from 36.4 % with X0626-T229 to 87.7 % for MT110061.

Summary:

Most entries had poor germination which negatively impacted plant stands and yields.
