AAC Darby was 6% higher yielding than Parata and 5% higher yielding than Carberry. AAC Darby matured 5 days earlier than Carberry and 1 day earlier than Parata. AAC Darby was similar in height to Glenn at 2 cm taller. The lodging score for AAC Darby was similar to the mean of the checks. The test weight of AAC Darby was similar to Carberry and the 1000-kernel weight was similar to Glenn and higher than Parata. AAC Darby had protein content only 0.07% lower than Carberry. AAC Darby expressed an intermediate resistant reaction to Fusarium head blight (FHB; Fusarium graminearum Schwabe). AAC Darby was moderately resistant to the prevalent races of stem rust ( Puccinia graminis Pers. f. sp. tritici Eriks. & E.
