AAC Warman Canada Western Red Spring wheat

Abstract

AAC Warman (BW1025) is a high-yielding Canada Western Red Spring (CWRS) wheat adapted to production in western Canada. AAC Warman was 3% higher yielding than Unity, the highest yielding check in the Central Bread Wheat Cooperative registration trials (2014–2016). Within the same test, AAC Warman was 11% higher yielding than Carberry, a popular CWRS wheat variety across the Canadian prairies. AAC Warman matured 3 d earlier than Carberry and a day later than Unity, the earliest maturing check. AAC Warman was shorter than Unity and had better stem strength compared with Unity; however, the lodging score for AAC Warman was higher than the mean of the checks. Over 3 yr of testing (2014–2016), the test weight and thousand-kernel weight of AAC Warman was similar to Carberry. The grain protein content of AAC Warman was 0.3% lower than both Unity and Carberry. AAC Warman was rated moderately resistant to Fusarium head blight (Fusarium graminearum Schwabe) and loose smut [Ustilago tritici (Pers.) Rostr.], resistant to leaf rust (Puccinia triticina Erikss.) and stem rust (Puccinia graminis Pers. f. sp. tritici Erikss. & E. Henn), moderately susceptible to stripe rust (Puccinia striiformis Westend.) and common bunt [Tilletia caries (DC.) Tul. & C. Tul.], and intermediately resistant to leaf spot complex. AAC Warman was resistant to orange wheat blossom midge (Sitodiplosis mosellana Géhin). Based on its milling and baking performance over 3 yr (2014–2016), as evaluated by the Grain Research Laboratory, Canadian Grain Commission, AAC Warman was registered under the CWRS market class.
