Origin & Breeding History: 'Robe Longue' is the result of the cross between 'A 7961-1' (female parent) and the hybrid 'QP87034.044' (male parent) that was made in 1996 at the Centre de la recherche Les Buissons, Pointe-aux-Outardes, Québec. The variety is characterized by its relative density and appearance in the mid-season trials.

Tests & Trials: Trials for 'Robe Longue' were conducted during the summer of 2008 at Pointe-aux-Outardes, Quebec. There were two replicates of 200 tubers spaced 25 cm apart.
