Variety Description

Varieties used for comparison: 'Chieftain' and 'Norland'

Summary: The lightsprout of 'AAC Fushia' is small whereas the lightsprout of 'Chieftain' is medium in size and that of 'Norland' is medium to large. In relation to the base, the tip of the lightsprout of 'AAC Fushia' is small whereas the tip of the lightsprout of the reference varieties is medium in size. The habit of the tip of the lightsprout of 'AAC Fushia' is closed whereas the habit is intermediate to open for 'Chieftain' and intermediate for 'Norland'. The extent of anthocyanin colouration of the stem is high and distributed along the entire stem for 'AAC Fushia' whereas the extent is medium along the entire stem of 'Chieftain' and low at the base of the stem only for 'Norland'. The upper side of the leaf of 'AAC Fushia' is medium green whereas the upper side of the leaf of the reference varieties is dark green. The intensity of anthocyanin colouration of the midrib on the upper side of the leaf is strong for 'AAC Fushia' whereas the intensity is medium for 'Chieftain' and absent or very weak for 'Norland'. The extent of anthocyanin colouration of the peduncle is high for 'AAC Fushia' whereas the extent is medium for the reference varieties. The shape of the tuber of 'AAC Fushia' is round whereas the shape of the tuber of the reference varieties is oval to oblong. The flesh of the tuber of 'AAC Fushia' is cream coloured whereas the flesh of the reference varieties is white.

Origin & Breeding History: 'AAC Fushia' (experimental designations '15005-07' and 'AR2010-11') originated from a cross conducted in Fredericton, New Brunswick, in 2002, between a selection designated 'N1700-8' , as the female parent, and the variety 'Chieftain', as the male parent. The breeding technique used was controlled fertilization of emasculated flowers. From the resulting progeny, 'AAC Fushia' 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 Fushia' 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.
