AAC Rivers (BW1143) is a hollow-stemmed, awned, and high yielding Canada Western Red Spring (CWRS) wheat cultivar suited to the growing conditions of Western Canada. AAC Rivers yielded 5653 kg ha-1 (11% higher than AAC Brandon and 19% higher yielding than Carberry) in the Central Bread Wheat Cooperative (CBWC) registration trials (2022-2024). AAC Rivers matured 91.5 days after seeding similar to AAC Brandon. AAC Rivers reached a height of 85 cm and was 3cm shorter than Glenn (91 cm). The lodging score of AAC Rivers was 2.6 (1-9 scale), which is better than AAC Brandon (3.2). The test weight of AAC Rivers was 79.9 kg hL-1 and 1000-kernel weight was 36.9 mg kernel-1. The grain protein content of AAC Rivers was 14.4%, comparable to AAC Brandon. AAC Rivers expressed an intermediate resistant reaction to Fusarium head blight (FHB; Fusarium spp.). AAC Rivers had optimal resistance to prevalent races of rusts in western Canada, with a resistant reaction to leaf rust (Puccinia triticina Erikss.) and stem rust (Puccinia graminis Pers. f. sp. tritici Eriks. & E. Henn), and moderately resistant reaction to stripe rust (Puccinia striiformis Westend). AAC Rivers had intermediate resistant reaction to common bunt [Tilletia caries (DC) Tul. & C. Tul.]. AAC Rivers was resistant to orange wheat blossom midge (OWBM) (Sitodiplosis mosellana Géhin). AAC Rivers was deemed to fit the CWRS wheat class by the Canadian Grain Commission (CGC) and registered with Canadian Food Inspection Agency (CFIA).
