The leaflets of 'Taurus' have a glossy upper side and veins with a medium depth whereas those of 'Atlantic' have a medium glossiness and deep veins. 'Taurus' has a taller plant height than 'Atlantic'. The extent of the anthocyanin colouration on the inner side of the corolla is absent or very low for 'Taurus' whereas it is high for 'Atlantic'. The intensity of the anthocyanin colouration on the inner side of the corolla is absent or very weak for 'Taurus' whereas it is medium for 'Atlantic'. The plants of 'Taurus' are late maturing whereas those of 'Atlantic' mature mid-season. The tubers of 'Taurus' have a yellow skin and light to medium yellow flesh whereas the skin is light beige and the flesh is cream in colour for the 'Atlantic' tubers.

Origin & Breeding History: The origin of 'Taurus' is the result of the cross made in 1995 between 'Panda' as the female parent and 'RZ-87-44' 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 'Taurus' 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.
