Origin & Breeding History: 'AAC Crimson Tide' (experimental designations AR2018-11, F13050, 16335-04) originated from a cross made between the variety 'Brigus' and 'Redsen' conducted at the Agriculture and Agri-Food Canada's Fredericton Research and Development Centre, in Fredericton, New Brunswick, in 2011. In 2012, 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 16335-04 was selected in 2013 from a single hill trial based on vine maturity, tuber numbers, tuber skin and flesh colour, tuber set, appearance, shape and size.

Tests & Trials: The comparative trial for 'AAC Crimson Tide' 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 normal dormancy breakage.
