The tip of the lightsprout of 'Purple Magic' has a closed habit and medium pubescence whereas it has an intermediate habit and dense pubescence in 'All Blue'. 'Purple Magic' has a glabrous leaflet blade at the apical rosette whereas it is pubescent for 'All Blue'. The extent of anthocyanin colouration of the flower bud is absent or very low for 'Purple Magic' whereas the extent is low for 'All Blue'. 'Purple Magic' has an absent to low extent of anthocyanin colouration on the peduncle whereas the extent is medium for 'All Blue'. The extent of the anthocyanin colouration on the inner side of the corolla is medium for 'Purple Magic' whereas it is high for 'All Blue'. The tubers of 'Purple Magic' have a long oval shape, with eyes that are at a shallow depth and a blue parti colour flesh whereas the tubers of 'All Blue' are long oval to long in shape, with eyes that are at a medium depth and a blue flesh.

Origin & Breeding History: The variety 'Purple Magic' originated from a cross between 'Premiere' as the female parent and 'Congo' as the male parent, made at the AFBI breeding station located in Loughgall, Co. Armagh, United Kingdom in 2003. Final selection took place in the field as a seedling in 2004. A recurrent selection technique was utilized in its development along with an intensive evaluation process of 6 years in private and public trials. Selection criteria included maturity, yield, disease resistance, processing traits and storage characteristics.

Tests & Trials: Trials for 'Purple Magic' were conducted during the 2013 growing season in Drummond, New Brunswick. Each variety plot 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 between rows. Plants were spaced 0.30 metres apart.
