'Tarnick' has strong anthocyanin colouration at the base of the light sprout with an high proportion of blue while it is low 'Snowden'. The corolla of 'Tarnick' is white whereas it is blue-violet in 'Atlantic'. 'Tarnick' has very weak intensity of anthocyanin colouration on inner surface of corolla while it is medium on 'Atlantic'. 'Tarnick' has dense pubescence on the light sprout base while it is medium on the reference varieties. 'Tarnick' has a medium number of root tips on the light sprout while it is many on 'Snowden' and few on 'Atlantic'.

Origin & Breeding History: 'Tarnick' (experimental designation 11926-2 and F95031) originated by the hybridization of 'AC Novachip' and 'Connestoga', made in Fredericton, in 1992. Selection criteria were adaptation, tuber type and chip quality.
Tests & Trials: Trials for 'Tarnick' were conducted at Potato Research Centre, Fredericton, New-Brunswick, in 2009. There were two replicates of 30 plants with a plant spacing of 30 cm.
