Summary: The lightsprout of 'Sundance' has a broad cylindrical shape with a medium number of root tips whereas 'Yukon Gold' has a spherical shape with few root tips. The lightsprout of 'Sundance' is medium to large in size and has medium to long lateral shoots whereas the lightsprout is small to medium in size and has short lateral shoots for 'Yukon Gold'. The intensity of anthocyanin colouration at the base and tip of the lightsprout is strong for 'Sundance' whereas it is medium for 'Yukon Gold'. The lightsprout base of 'Sundance' has sparse to medium pubescence whereas it is medium to dense for 'Yukon Gold'. The extent of anthocyanin colouration on the stem is absent for 'Sundance' whereas it is medium and halfway up the stem for 'Yukon Gold'. The plants of 'Sundance' have an absent or very low extent of anthocyanin colouration on the midrib of the upper side of the leaf whereas these are low in plants of 'Yukon Gold'. 'Sundance' has a shorter plant height than 'Yukon Gold'. The anthocyanin colouration on the inner side of the flower corolla of 'Sundance' is absent or very weak in intensity and its extent is absent or very low whereas the intensity of the anthocyanin colouration is weak to medium and the extent is high for 'Yukon Gold'. The plants of 'Sundance' mature mid to late season whereas those of 'Yukon Gold' matures early to mid-season. The tubers of 'Sundance' have eyes at a medium depth and a medium to dark yellow flesh whereas the tubers of 'Yukon Gold' have eyes at a shallow to medium depth and a light yellow flesh.

Origin & Breeding History: The origin of 'Sundance' (experimental designation HZ-97-185) is the result of the cross made in 1996 between 'RZ-89-2050' as the female parent and 'Quarta' 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 'Sundance' 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.
