'Gourmandine' has a small to medium sized lightsprout where the tip has a closed habit whereas 'Agata' has a medium to large lightsprout where the tip has a closed to intermediate habit. The intensity of anthocyanin colouration at the base of the lightsprout is medium to strong for 'Gourmandine' with the proportion of blue as absent or low whereas the intensity is absent to weak with a medium proportion of blue for 'Agata'. The extent of anthocyanin colouration on the stem is low along the entire stem for 'Gourmandine' whereas it is absent for 'Agata'. The leaves of 'Gourmandine' have a large outline whereas those of 'Agata' have a medium outline. The waviness of the leaflet margins for 'Gourmandine' is weak whereas it is medium for 'Agata'. 'Gourmandine' has a shorter plant height than 'Agata'. The frequency of inflorescences per plant for 'Gourmandine' is low to medium whereas it is absent or very low in 'Agata'. The plants of 'Gourmandine' mature in mid-season whereas those of 'Agata' mature late. The tubers of 'Gourmandine' have a long oval shape and have a medium yellow flesh whereas tubers of 'Agata' are short oval to oval in shape with a light yellow flesh. 'Gourmandine' has weak to medium anthocyanin colouration of the skin of the tuber in reaction to light whereas it is absent or very weak in 'Agata'.

Origin & Breeding History: The origin of 'Gourmandine' is the result of the cross made in 1992 between 'Charlotte' as the female parent and 'Estima' as the male parent at the Bretagne Plants Breeding Station in Hanvec, France. Selection criteria were negative mass selection agronomic characteristics and resistance to various diseases.

Tests & Trials: Tests and trials for 'Gourmandine' 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.
