UW-REC (SHERIDAN): The experiment was located at the University of Wyoming Research and Extension Center in Sheridan, Wyoming during 2007. The soil was a Wyarno clay loam (fine, montmorillonitic, mesic; Ustollic Haplargid), had a cropping history of: 2006, fallow; 2005, small grains; and 2004, fallow. The soil in the study area was prepared for planting by fall chiseling, followed by spring chiseling and roller harrowing. Ten wheat varieties were established in plots 5 by 20 feet using double disk openers set at a row spacing of 8 inches on 24 April. The seeding depth was 2.0 inches, and the seeding rate was 50 pounds of seed per acre. This location is a dry-land site with no irrigation. Rainfall during the growing period (1 April -31 July) was 7.42 inches. Subplots, 5 by 15 feet, were harvested on 07 August, using a Wintersteiger plot combine.
