‘UI Winchester’ (Reg. No. CV-1049, 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 developed using the bulk-pedigree selection method and was released for its improved resistance to stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici Eriks.) combined with its resistance to Hessian fly [Mayetiola destructor (Say)] and for its 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 ‘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.
