Interpretive Summary: Chukar winter club wheat (Triticum aestivum L.) was released because of its combination of yield potential, and disease resistance with the quality characteristics desired for club wheat. Yields of Chukar have been equal to or up to 5% better than those of 'Coda' club wheat and 'Madsen' soft white winter wheat over five years of multi-location yield trials in the Pacific Northwest. Chukar is a replacement to the club wheat 'Hiller' in intermediate to high rainfall environments when foot rot is a problem. Chukar is best suited to the intermediate to high rainfall zones of Washington State and North Idaho.

Technical Abstract: Chukar winter club wheat (Triticum aestivum L.) was developed by the USDA-ARS with assistance from the Washington Agricultural Experiment Station and the Oregon Agricultural Experiment Station. It was released in September of 2001 because of its combination of yield potential, and disease resistance with the quality characteristics desired for the club wheat market class. Yields of Chukar have been equal to or up to 5% better than those of 'Coda' club wheat and 'Madsen' soft white winter wheat over five years of multi-location yield trials in the Pacific Northwest. The test weight of Chukar has been good. Chukar is best suited to the intermediate to high rainfall zones of Washington State and North Idaho. Chukar is resistant to strawbreaker foot rot (caused by Tapesia yallundae Wallwork & Spooner) and carries the Pch1 gene for resistance, derived from Roazon. Chukar is resistant to stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici). and moderately resistant to Powdery Mildew (caused by Erysiphe graminis DC. f. sp. tritici Em.Marchal). Chukar is moderately susceptible to leaf rust (caused by Puccinia triticina Eriks.) and susceptible to dwarf bunt (caused by Tilletia controversa Kuhn in Rabenh. Ergot). The end use quality of Chukar is excellent as compared with other club wheat varieties. Chukar is a compliment to the club wheat 'Hiller' in intermediate to high rainfall environments when foot rot is a problem. It has exhibited consistent and stable yields, most likely because it possesses resistance to multiple diseases.
