© Her Majesty the Queen in Right of Canada 2019. AAC LeRoy (BW1049) is a hollow stemmed, awned, high-yielding Canada Western Red Spring (CWRS) wheat suited to the growing conditions in western Canada. AAC LeRoy was 10% higher yielding than Unity, the highest yielding check in the Central Bread Wheat Cooperative registration trials (2015–2017). Within the same test, AAC LeRoy was 13% higher yielding than Carberry, a popular CWRS wheat variety across the Canadian Prairies. AAC LeRoy matured 2 d earlier than Carberry and 1 d later than Unity, the earliest maturing check suited for eastern prairie growing conditions. AAC LeRoy was 6 cm shorter with better stem strength than Unity. The lodging score for AAC LeRoy was lower than the mean of the checks. The test weight of AAC LeRoy was similar to the mean of the checks. Over the 3 yr of testing (2015–2017), the 1000-kernel weight of AAC LeRoy was higher than all of the checks, with a grain protein content 0.6% units lower than Carberry. AAC LeRoy was rated as moderately resistant to Fusarium head blight (Fusarium graminearum Schwabe), leaf rust (Puccinia triticina Erikss.), stripe rust (Puccinia striiformis Westend.), and stem rust (Puccinia graminis Pers. f. sp. tritici Erikss. & E. Henn), including the Ug99 family of stem rusts. It also had a resistant reaction to loose smut [Ustilago tritici (Pers.) Rostr.] and an intermediately resistant reaction to common bunt [Tilletia caries (DC.) Tul. & C. Tul.]. AAC LeRoy was resistant to orange wheat blossom midge (Sitodiplosis mosellana Géhin). AAC LeRoy was registered under the CWRS market class.
