Origin & Breeding History: 'AAC Valkyrie' (experimental designations OT18-16 and X5643-1-089-2-2-B) originated from a cross between the variety 'S05-T6' and 'Dares', conducted in 2010 at Agriculture and Agri-Food Canada's Ottawa Research and Development Centre in Ottawa, ON. From 2010 to 2014, five generations were advanced using the pedigreed method of plant breeding. Selected F5 rows were bulked in 2014 with the variety being finally selected in 2019. Selection criteria included seed size, environmental adaptation and agronomic performance factors. Breeder seed produced in 2022.
Tests & Trials: The comparative trials for 'AAC Valkyrie', conducted in Ottawa, ON during the 2022 and 2023 growing seasons, were planted in a RCB design and consisted of 4 replicates for each variety. Plots consisted of 4 rows, 5 metres in length and a row spacing of 40 cm. The trial consisted of 500 plants per variety. For each variety, the plant height was based on four measurements per year. Mean differences were significant at the 5% probability level based on LSD values.
