The tip of the lightsprout in 'Purple Majesty' has an open habit while it is intermediate in 'All Blue'. 'Purple Majesty' has a semi-upright plant growth habit while it is spreading in 'All Blue'. The waviness of the margin of the leaflet in 'Purple Majesty' is medium while it is weak in 'All Blue'. 'Purple Majesty' has a high extent of anthocyanin colouration on the flower bud while it is medium in 'All Blue'. The frequency of inflorescences per plant in 'Purple Majesty' is high while it is medium in 'All Blue'. 'Purple Majesty' has a medium sized inflorescence while it is small in 'All Blue'. The extent of anthocyanin colouration on the peduncle of the inflorescence in 'Purple Majesty' is low while it is high in 'All Blue'. 'Purple Majesty' has a medium extent of anthocyanin colouration on the inner side of the corolla while it is high in 'All Blue'. The depth of the eyes on the tuber of 'Purple Majesty' is shallow while it is medium in 'All Blue'.

COROLLA: medium size, medium extent of anthocyanin colouration on the inner side, anthocyanin absent to very weak in intensity with a high proportion of blue
TUBER: short oval to oval, blue parti colour flesh
TUBER EYES: shallow
TUBER SKIN: blue, blue at base of eye
LIGHTSPROUT: large, narrow cylindrical, medium number of root tips, short lateral shoots

Origin & Breeding History: The origin of 'Purple Majesty' (experimental designation CO94165-3P/P) is the result of the cross made in 1994 between 'All Blue' and ND2008-2 at the San Luis Valley Research Centre, Colorado State Univeristy, Centre, Colorado. The selection criteria included yield potential, exceptional attractive tuber type and skin colour.
Tests & Trials: Tests and trials were conducted during the 2011 growing season in Drummond, New Brunswick. Plots consisted of 60 plants grown in a single row with a row length of 18.5 meters and a row spacing of 0.9 meters.
