The plants of 'Red Magic' have a higher extent of anthocyanin colouration on the stem and the midrib of the upper side of the leaf whereas these are low in plants of 'Red Pontiac'. 'Red Magic' has a shorter plant height than 'Red Pontiac'. The plants of 'Red Magic are late maturing whereas those of 'Red Pontiac' mature mid-season. The tubers of 'Red Magic' have a short oval to oval shape with eyes that are shallow to medium in depth whereas the tubers of 'Red Pontiac' are round with deep eyes. The tuber flesh of 'Red Magic' is cream coloured whereas it is white in 'Red Pontiac'.

Origin & Breeding History: The origin of 'Red Magic' is the result of the cross made in 1989 between 'Chieftain' and 'D191.103' in Ithaca, New York, USA. Selection criteria included appearance, disease and pest resistance, yield, cooking and frying quality.

Tests & Trials: Tests and trials for 'Red Magic' were conducted during the 2012 growing season in Drummond, New Brunswick. Each plot per variety consisted of 60 plants grown in a single row with a row length of 18.5 metres and a row spacing of 0.9 metres. Plants were spaced 0.30 metres apart.
