Abstract
'UI Sparrow' (Reg. No. CV-1134, PI 680612) soft white winter wheat (Triticum aestivum L.) was developed and released by the Idaho Agricultural Experiment Station in August 2016. Soft white winter wheat is an important wheat class grown in Idaho and the rest of Pacific Northwest. Resistance to stripe rust is critical for winter and spring wheat cultivars grown in the Pacific Northwest. Resistances to dwarf bunt and snow mold are also important traits for winter wheat cultivars produced in the dryland areas of the Pacific Northwest. UI Sparrow, tested under the experimental designations ID01108DH, is a semidwarf cultivar with strong straw, brown chaff, and long awns. It has excellent resistance to dwarf bunt, all-stage resistance to all tested predominant races of Puccinia striiformis f. sp. tritici except for PSTv-40, moderate to high levels of high-temperature adult-plant resistance to stripe rust, and high level resistance to snow mold. UI Sparrow was released as an alternative to Titan, 'Otto, and 'Xerpha' in the low-rainfall regions (<300 mm) and to 'Bobtail, 'SY Ovation, and 'UI-WSU Huffman' in the intermediate- (300-500 mm) and high-rainfall regions (>500 mm) of Idaho and Washington.
