Variety Description

Variety used for comparison: 'Yukon Gold'

Summary: The lightsprout of 'Perline' has a broad cylindrical shape whereas it is spherical for 'Yukon Gold'. The intensity of anthocyanin colouration at the base of the lightsprout is strong for 'Perline' whereas it is of medium intensity for 'Yukon Gold'. The lightsprout tip of 'Perline' has an open habit and is small in relation to the base whereas it has a closed habit and is medium sized in 'Yukon Gold'. 'Perline' has a semi-upright to spreading growth habit whereas it is upright to semi-upright for 'Yukon Gold'. The extent of anthocyanin colouration on the stem is absent for 'Perline' whereas it is medium and halfway up the stem for 'Yukon Gold'. 'Perline' has a shorter plant height than 'Yukon Gold'. The anthocyanin colouration on the inner side of the flower corolla of 'Perline' is absent or very weak in intensity and its extent is absent or very low whereas the intensity of the anthocyanin colouration is weak to medium and the extent is high for 'Yukon Gold'. The plants of 'Perline' matures very early to early whereas 'Yukon Gold' matures early to mid-season. The tubers of 'Perline' have a short oval shape and have a medium yellow flesh whereas 'Yukon Gold' tubers are round to short oval in shape with a light yellow flesh. The base of the eye of the tuber of 'Perline' is yellow whereas it is red on 'Yukon Gold'.

Origin & Breeding History: The origin of 'Perline' is the result of the cross made in 1997 between 'E90.79' as the female parent and 'Olivia' as the male parent at the Breeding Station de Recherche du Comite Nord in Bretteville du Grand Cause, France. Selection criteria included maturity, yield, disease resistance, processing traits, morphological traits and storage characters.

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