The leaf outline of 'AAC Confederation' is of medium size whereas the leaf outline of 'AAC Canada Gold-Dorée' is large. The plants of 'AAC Confederation' are shorter than the plants of 'Yukon Gold'. There is no anthocyanin colouration or proportion of blue in the anthocyanin colouration on the inner side of the corolla for 'AAC Confederation' whereas the intensity of anthocyanin colouration and proportion of blue are medium for 'Yukon Gold'. The tuber of 'AAC Confederation' has a short oval shape whereas it is oval for 'Yukon Gold' and round for 'AAC Canada Gold-Dorée'. The base of the eye of the tubers of 'AAC Confederation' is yellow whereas it is red for 'Yukon Gold'.

Origin & Breeding History: 'AAC Confederation' (experimental designations 'F07060' and '15357-25') originated from a controlled cross made in 2002, in Fredericton, New Brunswick, between the selection designated 'F87084', as the female parent, and the variety 'Rochdale Gold-Dorée', as the male parent. In 2006, true potato seed from this cross was sown in a greenhouse, and the resulting seedling tubers were planted in 2007 for evaluation and selection, at the Benton Research Substation of Agriculture and Agri-Food Canada, in Fredericton. 'AAC Confederation' was selected in 2007 from a single hill trial at the Benton Research Substation for its vine maturity, tuber appearance, shape and size.

Tests & Trials: The comparative trial for 'AAC Confederation' was conducted during the 2017 growing season at Agriculture and Agri-Food Canada's Fredericton Research and Development Centre, in Fredericton, New Brunswick. The trial consisted of 2 replicates of 30 plants per replicate for each variety, grown in two 7.5 metre length rows spaced 90 centimetres apart. The plants were spaced 25 centimetres apart within the row. The measurements were taken from 10 plants, or parts of plants, of each variety. Mean differences were significant at the 5% probability level based on LSD values.
