Origin & Breeding History: 'AAC Africadie' (experimental designations AR2015-16, V07148-2) originated from a cross made between the variety 'Cara' and experimental line FV12486-2 conducted at the Agriculture and Agri-Food Canada's Lethbridge Research and Development Centre, in Lethbridge, Alberta, in 2007. In 2008, the true potato seed resulting from the cross was sown in a greenhouse at the Agriculture and Agri-Food Canada's Lethbridge Research and Development Centre and the resulting seedling tubers planted at the Vauxhall Research Substation of Agriculture and Agri-Food Canada near Lethbridge, Alberta. A clone designated as V07148-2 was selected in 2009 from a single hill trial based on vine maturity, tuber numbers, tuber appearance, shape, size and flesh colour.

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