Interpretive Summary: Soft white winter wheat is an important wheat class grown in Idaho and the rest of Pacific Northwest (PNW). Resistance to stripe rust is critical for winter and spring wheat cultivars grown in the PNW. Resistances to dwarf bunt and snow mold are also important traits for winter wheat cultivars produced in the dryland areas of the PNW. ‘UI Sparrow’ soft white winter wheat was developed and released by the Idaho Agricultural Experiment Station in August 2016. UI Sparrow is a semidwarf cultivar with strong straw, brown chaff, and long awns. UI Sparrow has resistance to dwarf bunt, all-stage resistance to all tested predominant races of the stripe rust pathogen except for PSTv-40, and high level resistance to snow mold. UI Sparrow was released as an alternative for Eltan, Otto, and Xerpha in the low-rainfall regions (<300 mm) and for Bobtail, SY Ovation, and UI-WSU Huffman in the intermediate (300 - 500 mm) and high rainfall regions (>500 mm) of Idaho and Washington.

Technical Abstract: Soft white winter wheat is an important wheat class grown in Idaho and the rest of Pacific Northwest (PNW). Resistance to stripe rust , caused by Puccinia striiformis Westend. f. sp. tritici Erikss., is critical for winter and spring wheat cultivars grown in the PNW. Resistances to dwarf bunt, caused by Tilletia controversa J. G. Küln, and snow mold ,caused by Microdochium nivale (Fr.:Fr.) Samuels & I. C. Hallett and Typhula ishikariensis var idahoensis Imai, are also important traits for winter wheat cultivars produced in the dryland areas of the PNW. ‘UI Sparrow’ (Reg. No. CV-???, PI 680612) soft white winter wheat (Triticum aestivum L.) was developed and released by the Idaho Agricultural Experiment Station in August 2016. UI Sparrow, tested under the experimental designations IDO1108DH, is a semidwarf cultivar with strong straw, brown chaff, and long awns. UI Sparrow has resistance to dwarf bunt, all-stage resistance to all tested predominant races of P. striiformis f. sp. tritici except for PSTv-40, and high level resistance to snow mold. UI Sparrow was released as an alternative for Eltan, Otto, and Xerpha in the low-rainfall regions (<300 mm) and for Bobtail, SY Ovation, and UI-WSU Huffman in the intermediate (300 - 500 mm) and high rainfall regions (>500 mm) of Idaho and Washington.
