Origin & Breeding History: 'AAC Dale' (experimental designations OT16-02 and X5516-1-74-3-5-B) originated from the cross between 'OAC Champion' and 'AAC Mandor' made in Ottawa, Ontario in 2008. The population was advanced using the pedigree method of plant breeding. In 2012, selected F5 rows were grown in the field and bulked for further evaluation. Selection criteria included seed size, environmental adaptation and agronomic characteristics. 'AAC Dale' was tested as OT16-02 at multiple locations since 2014.
Tests & Trials: The comparative trials for 'AAC Dale' were conducted in Ottawa, Ontario during the 2019 and 2021 growing seasons. The trials were planted in a RCB design and consisted of 4 replicates for each variety. Plots consisted of 4 rows, each 5 metres in length with a row spacing of 40 cm. Each plot was sown at a density of 50 seeds per metre squared.
