'Robe Longue' has a larger lateral leaflet than the reference variety. The terminal and lateral leaflets of 'Robe Longue' have less waviness of the margin and are glossier than the reference variety. 'Robe Longue' has less inflorescences than the reference variety. The corolla of 'Robe Longue' is larger and has less anthocyanin colouration on the inner surface than the reference variety. The tuber of 'Robe Longue' has a weak anthocyanin colouration in reaction to light, a netted texture, prominent eyebrows with cream flesh whereas in 'Shepody' it has a medium anthocyanin colouration in reaction to light, a rough texture, slight prominence of eyebrows with white flesh. The light sprout of 'Robe Longue' is small and spherical whereas it is medium and broad cylindrical in the reference variety. The base of the light sprout of 'Robe Longue' has weaker anthocyanin colouration and is less pubescent than the reference variety.

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.
