AAC Redstar is an early maturing, high-yielding hard red spring wheat (Triticum aestivum L.) cultivar that is well adapted to the northern Canadian Prairies and eligible for grades of Canada Western Red Spring (CWRS) wheat. Over 3 yr (2016–2018) of testing in the Parkland Wheat Cooperative registration trials, AAC Redstar was 11% higher yielding than AC Splendor, 6% higher than Parata, and 4% higher than Glenn and Carberry. AAC Redstar matured 3 d earlier than Glenn, 2 d earlier than Carberry, and had similar maturity to Parata. AAC Redstar was shorter than all checks except Carberry and had better lodging resistance compared with all the check cultivars in the registration trial. The test weight and thousand-kernel weight of AAC Redstar were similar to Carberry. The grain protein concentration of AAC Redstar was 0.2% lower than Carberry. AAC Redstar was rated moderately resistant to Fusarium head blight, leaf rust, stripe rust, and common bunt. AAC Redstar had resistant reactions to loose smut and stem rust. AAC Redstar was registered under the CWRS market class.
