AAC Hassler (PT496) is an early maturing, high yielding, awned, and hollow stemmed Canada Western Red Spring (CWRS) wheat (Triticum aestivum L.) cultivar suited to growing conditions in the northern Canadian Prairies. AAC Hassler yielded 8% more than Glenn, 6% more than Parata, and 6% more than Carberry in the Parkland Wheat Registration Trials (2019–2021). AAC Hassler matured 4 days earlier than Carberry and had similar maturity as Parata. AAC Hassler had similar height to Glenn and the lodging score was similar to Parata. The test weight of AAC Hassler was 2% lower than the mean of the checks and the thousand kernel weight was similar to Glenn. AAC Hassler had protein content 0.1% higher than Carberry. AAC Hassler expressed an intermediate resistant reaction to Fusarium head blight (FHB; Fusarium graminearum Schwabe). AAC Hassler was moderately resistant to the prevalent races of stem rust (Puccinia graminis Pers. f. sp. tritici Eriks. & E. Henn) and moderately susceptible to common bunt (Tilletia caries (DC) Tul. & C. Tul.). It was resistant to prevalent races of leaf rust (Puccinia triticina Erikss.) and stripe rust (Puccinia striiformis Westend). AAC Hassler was susceptible to orange wheat blossom midge (Sitodiplosis mosellana Géhin). AAC Hassler was registered under the CWRS class.
