Abstract
"Otto" is a soft white winter wheat cultivar recently released by WSU with moderate resistance to eyespot (strawbreaker) foot rot and stripe rust. "Xerpha" is a popular, high yielding soft white winter wheat cultivar that is susceptible to eye-spot foot rot and moderately susceptible to stripe rust. Four on-farm tests (OFTs) were established across the dryland cropping region of Adams County, Washington, to investigate the performance of Otto in comparison to Xerpha with and without fungicide application. OFTs were conducted as strip-split block designs. Otto yielded 65.4 bu/ac, significantly higher than Xerpha at only 63.0 bu/ac. A significant variety x fungicide interaction shows across locations that fungicide application on Xerpha significantly improved grain yield by 5.7 bu/ac, or 9%, but only improved 2.2 bu/ac, or 3%, on Otto. These results are consistent with higher levels of disease resistance in Otto.
