AAC Prevail Canada Western Red Spring wheat

AAC Prevail (BW462) is a high-yielding spring wheat (Triticum aestivum L.) with high protein content and is adapted to the growing conditions in the Canadian prairies. AAC Prevail yielded similar to Unity, the highest yielding check in the Central Bread Wheat Cooperative Registration tests (2010–2012). Over 3 yr of testing in Manitoba (zone 1), AAC Prevail achieved 1.5% higher yield than Unity whereas in Saskatchewan (zone 2), it yielded 98.4% of Unity. AAC Prevail matured 1 d later than Unity and McKenzie, the earliest maturing checks. AAC Prevail was taller than all the checks but had better lodging resistance than Unity, McKenzie, and 5603HR. The test weight and kernel weight of AAC Prevail were similar to the checks. AAC Prevail was rated resistant to leaf rust (Puccinia triticina Erikss.) and moderately resistant to stem rust (Puccinia graminis f. sp. tritici) but susceptible to bunt [Tilletia caries (DC) Tul. & C. Tul.] and loose smut [Ustilago tritici (Pers.) Rostr.]. The Fusarium head blight (Fusarium graminearum Schwabe) rating was intermediate for visual rating index but the combined incidence, severity, and deoxynivalenol rating was moderately resistant. During 3 yr of evaluation, AAC Prevail was resistant to orange wheat blossom midge (Sitodiplosis mosellana Géhin). AAC Prevail was registered under the Canada Western Red Spring class for its high protein as well as good milling and baking performance.
