Varieties used for comparison: 'Snowden' and 'Carrera'
Summary: The lightsprout of 'Oriana' is medium sized whereas it is large for 'Carrera'. The intensity of the anthocyanin colouration at the base of the lightsprout of 'Oriana' is weak to medium whereas it is medium to strong for the lightsprout of 'Carrera'. The lightsprout tip of 'Oriana' has an intermediate habit, very weak to weak intensity of anthocyanin colouration and sparse pubsescence while the lightsprout tip of 'Carrera' has a closed habit, weak to medium intensity of anthocyanin colouration and medium to dense pubescence. The lightsprout of 'Oriana' has few root tips while that of 'Snowden' has a medium number. The leaf of 'Oriana' is medium green while that of 'Snowden' is light green. The plant of 'Oriana' is shorter than that of 'Snowden'. The frequency of flowers per plant is low for 'Oriana' while it is medium for 'Snowden'. The extent of anthocyanin colouration on the inner side of the flower corolla is absent or very weak for 'Oriana' while it is medium for 'Carrera'. The plant of 'Oriana' matures very early to early while both reference varieties mature mid-season. The anthocyanin colouration of skin in reaction to light on the tuber of 'Oriana' is absent to very weak while it is medium to strong for 'Snowden' and weak to medium for 'Carrera'.

Origin & Breeding History: The origin of 'Oriana' (experimental designation RZD-95-1683) is the result of the cross made in 1994 between 'Vivaldi' as the female parent and 'BL81-2-259' as the male parent at the HZPC Research & Development Centre in Metslawier, The Netherlands. Selection criteria included internal and external quality, yield and resistances against different diseases and pests.
Tests & Trials: Tests and trials for 'Oriana' 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 between rows. Plants were spaced 0.30 metres apart.
