Variety Description

Varieties used for comparison: 'Atlantic' and 'Superior'

Summary: The extent of anthocyanin colouration on the midrib of the upper side of the leaf and the peduncle is low to medium for 'Vigor' while it is absent or very low for the reference varieties. The corolla of 'Vigor' has medium to strong anthocyanin colouration while the corolla of the 'Atlantic' has weak anthocyanin and the corolla of 'Superior' has weak to medium anthocyanin. The tuber of 'Vigor' has medium yellow flesh while the tubers of the reference varieties have cream coloured flesh. The light sprout base of 'Vigor' has strong anthocyanin colouration with a high proportion of blue while the light sprout base of 'Atlantic' has medium to strong anthocyanin with a medium proportion of blue and the light sprout base of 'Superior' has medium anthocyanin with a medium proportion of blue. The light sprout tip of 'Vigor' has strong anthocyanin colouration while the light sprout tip of 'Atlantic' has weak to medium anthocyanin and the light sprout tip of 'Superior' has medium anthocyanin.

Origin & Breeding History: The variety 'Vigor' originated from a cross between 'Agria' and 'Wischip', made at Agriculture & Agri-Food Canada, Lethbridge Research Centre in Lethbridge, Alberta in 1994. The true potato seed was sown in the greenhouse in 1995 at Lethbridge and the resulting seedling tubers were planted at the Vauxhall Research Substation in 1996 for selection. The V1002-2 (Vigor) clone was selected in 1996 and progressed through 4-hill, 10-hill and 50-hill generation stages of selection and evaluation at Vauxhall in 1997 to 1999. This was followed by evaluation in the Western Canadian Regional Potato Trials in 2000 to 2003. Commercial evaluation by the Western Potato Consortium-A started in 2004.

Tests & Trials: Trials for 'Vigor' were conducted during the summer of 2010 at the Potato Research Centre in Fredericton, New Brunswick. Plots consisted of two replications with a row length of 9.15 meters and a row spacing of 91 cm. Plants were spaced 30 cm apart within the row. There were 60 plants per variety in the trial.
