'AAC Cinderella' has a small leaf outline whereas the reference varieties have a medium size outline. The second pair of lateral leaflets for 'AAC Cinderella' is small whereas it is medium for the reference varieties. 'AAC Cinderella' has a medium frequency of coalescence of the terminal and lateral leaflets whereas it is absent or very low for the reference varieties. The plant of 'AAC Cinderella' is shorter than that of the reference varieties. The frequency of inflorescences per plant is low for 'AAC Cinderella' whereas it is high for 'Congo'. 'AAC Cinderella' has small inflorescences whereas those of 'Adirondack Red' are medium sized and those of 'Congo' are medium to large. The extent of anthocyanin colouration of the peduncle is absent or very low for 'AAC Cinderella' whereas the extent is medium for the reference varieties.

Origin & Breeding History: 'AAC Cinderella' (experimental designations 'AR2012-06_F06053' and 15247-22) originated from the cross of 'Congo' and PA99P20-2 made in 2004 in Fredericton, New Brunswick. In 2006, the progeny designated as 15247-22 was selected. Selection criteria were clonal selection for adaptation, tuber type, flesh colour and fresh market potential.

Tests & Trials: The comparative trial for 'AAC Cinderella' was conducted during the 2016 growing season at Agriculture and Agri-Food Canada's Fredericton Research and Development Centre in Fredericton, New Brunswick. The trial consisted of 2 replicates with 30 plants per variety in each replicate, grown in two 7.5 metre length rows spaced 90 centimetres apart. Plants were spaced 25 centimetres apart in the row. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety. Mean differences were significant at the 5% probability level based on paired Student's t-tests.
