Variety Description

Variety used for comparison: 'Snowden'

Summary: The intensity of anthocyanin colouration at the base of the lightsprout is strong for 'Servane' whereas it is weak for 'Snowden'. The base of the lightsprout of 'Servane' has an absent to sparse pubescence whereas 'Snowden' has sparse to medium pubescence. The tip of the lightsprout of 'Servane' has a medium pubescense whereas 'Snowden' has sparse pubescence. The lightsprout of 'Servane' has a few root tips whereas that of 'Snowden' has a medium number of root tips. The foliage structure of 'Servane' is an intermediate type whereas 'Snowden'is a leaf type. 'Servane' has an upright growth habit whereas it semi-upright for 'Snowden'. The extent of anthocyanin colouration along the entire stem of 'Servane' is medium while it is absent on 'Snowden'. The plants of 'Servane' have a low extent and weak intensity of anthocyanin colouration on the the midrib of the upper side of the leaf whereas plants of 'Snowden'have an absent or very low extent and absent or very weak intensity. The frequency of coalescence of the terminal and lateral leaflets of 'Servane' is medium to high whereas it is absent for 'Snowden'. The leaflet blade at the apical rosette is pubescent for 'Servane' whereas it is glabrous in 'Snowden'. The frequency of flowers per plant is medium to high for 'Servane' whereas it is absent or very low for 'Snowden'. 'Servane' has medium sized inflorescences whereas those of 'Servane' are small. The tubers of 'Servane' have a long oval shape with a yellow skin and a light yellow flesh whereas the tubers of 'Snowden' are round with a light beige skin and a white flesh.

Origin & Breeding History: The variety 'Servane' originated from a cross between 'G92TP026027' as the female parent and 'Felsina' as the male parent, made at Châteauneuf-du-Faou, France in 1998. Seed of the cross was sown, transplanted into 9 cm pots and grown in the greenhouse during the spring of 1999. One tuber was harvested and planted in the field in 2000. Four tubers were harvested and in 2001 four hill plots were planted from which 30 tubers were harvested. In 2002, 18 seed tubers were planted in the field for seed production and 8 tubers were used for testing. From 2003 to 2007, testing was conducted in France, Italy, the United Kingdom, Spain, the Netherlands and Germany. Further evaluations were conducted in Cyprus, Egypt, Portugal and Tunisia in 2008 and 2009. Criteria used in the selection process included pest resistance, yield, cooking and frying quality, dry matter content, storability and visual impression.

Tests & Trials: Trials for 'Servane' were conducted during the 2013 growing season in Drummond, New Brunswick. Each variety plot 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.
