Variety used for comparison: 'Sylvana'
Summary: The lightsprout tip of 'Loane' is of medium size in relation to the base with dense pubescence at the base and a medium number of root tips and whereas the lightsprout tip of 'Sylvana' has a small size in relation to the base with medium pubescence at the base and a few root tips. The intensity of the anthocyanin colouration of the lightsprout tip for 'Loane' is absent or very weak whereas it has a weak to medium intensity in 'Sylvana'. 'Loane' has an upright growth habit whereas it is semi-upright in 'Sylvana'. The extent of anthocyanin colouration on the stem is high for 'Loane' whereas it is medium for 'Sylvana'. 'Loane' has a light green leaf whereas it is medium green for 'Sylvana'. 'Loane' has a low frequency of coalescence of the terminal and lateral leaflets whereas it is absent or very low in 'Sylvana'. The glossiness of the leaflet for 'Loane' is dull on the upper side while it is medium for 'Sylvana'. 'Loane' has a shorter plant height than 'Sylvana'. The extent of the anthocyanin colouration on the inner side of the corolla is medium for 'Loane' whereas it is low for 'Sylvana'. 'Loane' has a medium sized corolla whereas 'Sylvana' has a large corolla.

Origin & Breeding History: The variety 'Loane' originated from a cross between 'Arinda' as the female parent and 'Valor' as the male parent, made at Châteauneuf-du-Faou, France in 1993. Seed of the cross was sown, transplanted into 9 cm pots and grown in the greenhouse during the spring of 1998. One tuber was harvested and planted in the field in 1999. Four tubers were harvested and in 2000 four hill plots were planted from which 30 tubers were harvested. In 2001, 18 seed tubers were planted in the field for seed production and 4 tubers were planted in north Portugal for testing. From 2002 to 2006, testing was conducted in France, Italy, Portugal, Spain, Cyprus,
Morocco, Tunisia and Israel. Further evaluations were conducted in Egypt and the United Kingdom in 2007 and 2008. 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 'Loane' 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. The measured characteristics were based on 10 measurements per variety. Mean differences were significant at the 5% probability level based on a paired Students t-test.
