Varieties used for comparison: 'Rochdale Gold-Dorée' and 'Yukon Gold'
Summary: The lightsprout of 'AAC Glossy' is large with a large tip in relation to the base whereas the lightsprout of both reference varieties is medium in size with a tip that is medium sized in relation to the base. The lighsprout of 'AAC Glossy' has many root tips and long lateral shoots whereas the lightsprout of 'Rochdale Gold-Dorée' has a medium number of root tips and short lateral shoots and the lightsprout of 'Yukon Gold' has few root tips and short lateral shoots. The plants of 'AAC Glossy' are taller than the plants of both reference varieties. The extent of anthocyanin colouration of the stem of 'AAC Glossy' is low along the entire stem whereas the extent is absent or very low and only at the base of the stem for 'Rochdale Gold-Dorée' and the extent is low halfway up the stem only for 'Yukon Gold'. The presence of secondary leaflets is strong for 'AAC Glossy' whereas the presence is medium for both reference varieties. The extent of anthocyanin colouration of the midrib on the upper side of the leaf is low for 'AAC Glossy' whereas the extent is absent or very low for both reference varieties. The corolla of 'AAC Glossy' is small whereas the corolla of both reference varieties is medium in size. The time of maturity of the plants of 'AAC Glossy' is very early whereas the time of maturity of the plants of both reference varieties is mid-season. The shape of the tuber of 'AAC Glossy' is round whereas the tuber of 'Yukon Gold' is oval. The depth of the eyes of the tuber is medium deep for 'AAC Glossy' whereas the depth of the eyes is shallow for both reference varieties. The flesh of the tuber of 'AAC Glossy' is cream coloured whereas the flesh of the tuber is medium yellow for 'Rochdale Gold-Dorée' and light yellow for 'Yukon Gold'.

Origin & Breeding History: 'AAC Glossy' (experimental designations 'F05060' and 'AR2010-10') originated from a cross conducted in Fredericton, New Brunswick, in 2002, between the variety 'Rochdale Gold-Dorée' , as the female parent, and a selection designated 'N1682-28', as the male parent. The breeding technique used was controlled fertilization of emasculated flowers. From the resulting progeny, 'AAC Glossy' was selected in 2005 during the first field generation for its adaptation to Canadian growing conditions and potato production systems, tuber type and fresh market potential.
Tests & Trials: The comparative trial for 'AAC Glossy' was conducted during the 2015 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. The measurements were taken from 10 plants, or parts of plants, of each variety.
