Interpretive Summary: Global initiatives to develop varieties resistant to new races of rust are the first line in defending farmers from crop loss. UI Winchester hard red spring wheat carries resistance to current races of stripe rust and Hessian fly. It is a cultivar for growers in the Pacific Northwest who struggle with these pests. Seed of the publicly released cultivar is available through Idaho Foundation Seed.

Technical Abstract: ‘UI Winchester’ (PI 642362) hard red spring wheat (Triticum aestivum L.) was developed by the Idaho Agricultural Experiment Station and released in July 2009. UI Winchester was released for its improved stripe rust (Puccinia striiformis Westend f. sp. tritici) resistance combined with resistance to Hessian fly (Mayetiola destructor Say), comparable or better yield and end-use quality performance compared with the three widely adapted hard red spring wheat cultivars ‘Jefferson’ (PI 603040), ‘Jerome’ (PI 632712), and ‘Westbred 936’. UI Winchester is named after the town of Winchester, Idaho. It was tested under experimental numbers A9356S and IDO578, and has the pedigree of ‘Westbred 926’/WA7702. UI Winchester is adapted to both irrigated and rainfed conditions, but it is better adapted to the rainfed production systems of the intermountain zone of the Western United States.
