Randhawa, H. S., Graf, R. J. and Sadasivaiah, R. S. 2014. AAC Chiffon soft white spring wheat. Can. J. Plant Sci. 94: 1303-1308. AAC Chiffon is a soft white spring wheat (Triticum aestivum L.) cultivar that meets the end-use quality specifications of the Canada Western Soft White Spring (CWSWS) class. AAC Chiffon is well-adapted to the irrigated wheat growing regions of southern Alberta and southern Saskatchewan, and for rain-fed production in the western prairies. Based on data from the Western Soft White Spring Wheat Cooperative registration trials from 2008 to 2011, AAC Chiffon exhibited higher grain yield than the check cultivars, similar maturity, and taller stature with moderate straw strength. AAC Chiffon expressed resistance to the prevalent races of stripe rust, intermediate responses to powdery mildew, kernel black point and leaf rust, and susceptibility to stem rust, common bunt, loose smut and Fusarium head blight. Based on end-use quality analysis performed by the Grain Research Laboratory of the Canadian Grain Commission, AAC Chiffon was eligible for grades of CWSWS wheat.
