Origin & Breeding History: 'AAC Invest 1605' (experimental designations OT13-04 and X5165-1-28-3-5-B) originated from the cross between X3390-B-B-B-21 and X3144-48-1-B-1, resulting in the line OT05-19 which was then crossed with Kamichis. The crosses were conducted in Ottawa, Ontario with the final cross occuring in 2005. The population was advanced using the pedigree method of plant breeding. In 2009, selected F5 rows were grown in the field and bulked for further evaluation. Selection criteria included protein content, adaptation and agronomic characteristics. 'AAC Invest 1605' was tested as OT13-04 at multiple locations in Canada from 2011 to 2015.

Tests & Trials: The comparative trials for 'AAC Invest 1605' were conducted in Ottawa, Ontario during the 2017 and 2018 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. The seed weight was based on four measurements per variety per year. Mean differences were significant at the 5% probability level based on LSD values.
