Origin & Breeding History: 'AAC Red Berry' (experimental designations AR2014-13, F09078, 15631-72) originated from a cross made between the variety 'AC Red Island' and experimental line F02010 conducted at the Agriculture and Agri-Food Canada's Fredericton Research and Development Centre, in Fredericton, New Brunswick, in 2007. In 2009, 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. A clone designated as 15631-72 was selected in 2010 from a single hill trial based on vine maturity, tuber numbers, tuber set, appearance, shape and size.

Tests & Trials: The comparative trial for 'AAC Red Berry' 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. Lightsprout characteristics were assessed on 6 tubers harvested from the comparative trial and observed approximately five months after harvest following natural dormancy breakage.
