Origin & Breeding History: 'AAC Eastern Russet' (experimental designations AR2017, F12022 and 16040-03) originated from a cross made between the varieties 'Innovator' and 'Tenace' conducted at the Agriculture and Agri-Food Canada's Fredericton Research and Development Centre, in Fredericton, New Brunswick, in 2009. 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 Ridge Research Substation of Agriculture and Agri-Food Canada near Woodstock, New Brunswick, in 2011. A clone designated as 16040-03 was selected in 2011 from a single hill trial based on vine maturity, tuber appearance, shape, size and flesh colour.

Tests & Trials: The comparative trial for 'AAC Eastern Russet' was conducted during the 2019 growing season at Agriculture and Agri-Food Canada's Fredericton Research and Development Centre, in Fredericton, New Brunswick. The trial consisted of 2 replicates per variety arranged in a RCB design. Each replicate consisted of 40 plants in a 12 metre length row. The rows were spaced 90 centimetres apart and the plants were spaced 25 centimetres apart within the row.
