AAC Connery Hard Red Spring Wheat

Abstract

AAC Connery, a doubled haploid awnless hard red spring wheat (Triticum aestivum L.), was similar in grain yield to CDC Osler and significantly higher yielding than the other check cultivars Katepwa, CDC Teal and AC Splendor. Wheat and flour protein concentrations were within the range of the checks. AAC Connery matured significantly later than AC Splendor and in a comparable number of days as Katepwa, CDC Teal, and CDC Osler. AAC Connery was significantly shorter than all of the checks and was significantly more resistant to lodging than Katepwa, AC Splendor and CDC Osler. AAC Connery had significantly heavier kernel weight than Katepwa, CDC Teal and AC Splendor. The test weight of AAC Connery was within the range of the checks. End-use quality specifications of AAC Connery are suitable for the Canada Western Red Spring wheat market class. AAC Connery expressed moderate resistance to Fusarium head blight, an improvement over the checks, resistance to prevalent races of stem rust and yellow rust, and moderate resistance to leaf rust, loose smut, and common bunt.
