Developing wheat ( Triticum aestivum L.) cultivars with high yield, desirable end‐use quality, and resistance to prevalent diseases are the major goals for the breeding programs in the Pacific Northwest region of the United States and the world. ‘UI SRG’ (Reg. No. CV‐1066, PI 660546) hard red winter wheat was developed by the Idaho Agricultural Experiment Station using a modified backcross breeding procedure. UI SRG was derived from a BC 1 F 7 line from the backcross ‘Utah 100’*2/‘Boundary’ and tested under experimental numbers A971065W‐J‐4 and IDO656. UI SRG was released in 2010 for its improved resistance to stripe rust (caused by Puccinia striiformis Westend f. sp. tritici ) combined with superior yield and resistance to dwarf bunt (caused by Tilletia contraversa Kühn) and stem rust (caused by P. graminis Pers: Pers. f. sp. tritici Eriks. & E. Henn) (local and TTKS races). UI SRG is best adapted to rainfed production in the intermountain zone of the western United States and is targeted to replace the stripe rust–susceptible cultivar ‘Deloris’ and the lower‐yielding older cultivars Utah 100 and ‘Finley’. Milling and baking quality of UI SRG is not significantly different from that of the best‐quality check cultivars ‘DW’ and Deloris.
