The base of the light sprout of 'Arbor Globe' has medium pubescence while 'Superior' has absent or very sparse pubescence. The lightsprout tip of 'Arbor Globe' has an intermediate habit, absent or very weak intensity of anthocyanin colouration and medium pubescence while the light sprout tip of 'Atlantic' has an intermediate habit, weak intensity of anthocyanin colouration and dense pubescence and the light sprout tip of 'Superior' has a closed habit, strong intensity of anthocyanin colouration and sparse pubescence. 'Arbor Globe' has a taller plant height than 'Atlantic'. 'Arbor Globe' has an absent or very weak intensity of anthocyanin colouration on the inner side of the corolla while it is medium in the reference varieties. The extent of anthocyanin colouration on the inner side of the corolla in 'Arbor Globe' is absent or very low while it is high in 'Atlantic' and medium for 'Superior'.

Origin & Breeding History: The origin of 'Arbor Globe' (experimental designation PR90-18-3) is the result of a cross made in 1990 between 'LaBelle' and ND860-2 at Privar Farm Inc., North Wiltshire, Prince Edward Island. 'LaBelle' was released by Louisiana State University and ND860-2 was a seedling from North Dakota State University. Selection criteria included vigorous growth habit, maturity, high pay yields, attractive tubers, high dry matter content, good eating quality and good processing quality for both chips and fries.

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.
