Colorado State University Technical Report. TR23-3:1-58.

Interpretive Summary: Colorado State University tests wheat performance of new varieties in eastern Colorado under a broad range of dryland environmental conditions (41 varieties across six northeast and five southeast trials) and irrigated conditions (22 varieties across three northeast trials). The variety trials included a combination of public and private varieties and experimental lines. Seed companies with entries in the variety trials included AgriPro Syngenta, CROPLAN, and Meridian Seeds. There were entries from the Colorado marketing organization PlainsGold, the Kansas Wheat Alliance, Montana State University, Oklahoma Genetics, Inc., and Crop Research Foundation of Wyoming. Varieties were planted at 700,000 seeds per acre for dryland trials and 1.2 million seeds per acre for irrigated trials. Yield is corrected to 12% moisture. Variety trial plot weight, test weight, and grain moisture content information, obtained from a Harvest Master H2 weighing system on a plot combine, are reported.

Technical Abstract: Colorado State University researchers provide current, reliable, and unbiased wheat variety information to Colorado producers. Support of our research keeps public variety testing thriving in Colorado. Our work in Colorado is possible due to the support and cooperation of the entire Colorado wheat industry, the Colorado Wheat Administrative Committee, the Colorado Wheat Research Foundation, seed companies who enter varieties, and Colorado farmers who donate their resources and time to host wheat variety trials. We test under a broad range of environmental conditions to best determine expected performance of new varieties. We have a regional uniform variety testing program, meaning that dryland varieties entered in our northeast region are tested across our six test locations in northeast Colorado and varieties entered in our southeast region are tested across our five tests in southeast Colorado. All irrigated varieties are tested in all three irrigated trials across northeast Colorado. There were 41 varieties, including experimental lines, across the two regions of the 11 total dryland trials. The three irrigated trials each had 22 varieties. The variety trials included a combination of public and private varieties and experimental lines. Seed companies with entries in the variety trials included AgriPro Syngenta, CROPLAN, and Meridian Seeds. There were entries from the Colorado marketing organization PlainsGold, the Kansas Wheat Alliance, Montana State University, Oklahoma Genetics, Inc., and Crop Research Foundation of Wyoming. All dryland and irrigated trials were planted in a randomized complete block design with three replicates. Plot sizes were approximately 150 ft2 (except the Fort Collins irrigated trial, which was 80 ft2) and all varieties were planted at 700,000 seeds per acre for dryland trials and 1.2 million seeds per acre for irrigated trials. Plot sizes for the COFT ranged from 0.20 to 1.5 acres per variety in side-by-side strips with seeding rates conforming to the seeding rate used by the collaborating farmer. Yield is corrected to 12% moisture. Variety trial plot weight, test weight, and grain moisture content information were obtained from a Harvest Master H2 weighing system on a plot combine.
