Registration of 'KS Hamilton' hard red winter wheat

Hard winter wheat (Triticum aestivum L.) is a major crop in semi-arid western Kansas. The objective of this research was to develop a hard red winter wheat cultivar for western Kansas with high grain yield potential, good baking quality, and resistance to the important diseases in this region, including Wheat streak mosaic virus, Barley yellow dwarf virus, stripe rust, leaf rust, stem rust, and Hessian fly. 'KS Hamilton' (Reg. no. CV-1188, PI 699003) hard red winter wheat was developed by the wheat breeding program at the Agricultural Research Center-Hays, Kansas State University, and released by the Kansas Agricultural Experiment Station in 2020. KS Hamilton was selected from a three-way cross of KS08HW176-4//'Bill Brown'/KS08HW61-2. It was released for the dryland production in western Kansas. KS Hamilton was developed using a modified bulk breeding method. KS Hamilton is an F-6-derived line and was tested in yield trials for 6 yr. KS Hamilton has an intermediate maturity and plant height and an average straw strength. It has moderate tolerance to grain shattering and good winterhardiness. KS Hamilton has high grain yield potential in western Kansas and a good disease resistance package, including resistance to Wheat streak mosaic virus, stem rust, and Hessian fly; moderate resistance to Barley yellow dwarf virus; and intermediate resistance to stripe and leaf rusts. KS Hamilton has an average test weight and an above-average baking quality.
