Komar was selected in 1923 from a cross of Marquis and Kota made in 1918 at the North Dakota Agricultural Experiment Station. It was registered as an improved variety in Iowa in 1931 due to high yields and stem rust resistance. It was distributed in Colorado in 1931 but was not recommended there. However, Utah State Cooperative Extension more recently indicates that Komar is well adapted to dry land (non-irrigated) production.
