Origin & Breeding History: 'AAC Burcadie' (experimental designations AR2015-03, F10012, 15675-02) originated from a cross made between experimental lines F93043 and F00102 conducted at the Agriculture and Agri-Food Canada's Fredericton Research and Development Centre, in Fredericton, New Brunswick, in 2008. In 2008, 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 2009. A clone designated as 15675-02 was selected in 2009 from a single hill trial based on vine maturity, tuber numbers, tuber appearance, shape and size.

Tests & Trials: The comparative trial for 'AAC Burcadie' 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.
