Origin & Breeding History: 'AAC Blaze' (experimental designations AR2016-15, F11046, 16123-07) originated from a cross made between the experimental line AT12897 and variety 'Redsen' conducted at the Agriculture and Agri-Food Canada's Fredericton Research and Development Centre, in Fredericton, New Brunswick, in 2003. In 2010 the true potato seed resulting from the cross was sown in a greenhouse at the Agriculture and Agri-Food Canada's Fredericton Research and Development Centre and the resulting seedling tubers planted at the Benton Research Substation of Agriculture and Agri-Food Canada near Fredericton, New Brunswick in 2011. A clone designated as 16123-07 was selected in 2011 from a single hill trial based on vine maturity, tuber numbers, tuber skin colour, tuber set, appearance, shape and size.

Tests & Trials: The comparative trial for 'AAC Blaze' was conducted at Agriculture and Agri-Food Canada's Fredericton Research and Development Centre, in Fredericton, New Brunswick during the 2021 growing season. The field trial consisted of 2 replicates per variety, arranged in a RCB design. Each replicate was a 12 metre long row containing 40 plants spaced 0.25 metres apart with 0.9 metre inter-row spacing. Measurements were taken from 10 plants, or 10 parts of plants, of each variety. The mean differences were significant at the 5% probability level based on a paired Student's t-test. Lightsprout characteristics were assessed on 6 tubers harvested from the comparative trial and observed approximately five months after harvest following normal dormancy breakage.
