Origin & Breeding History: The potato variety 'Ampera' was selected from the F1 progeny of the crossing 'Aguti x Ponto' made in Lüneburg, Germany in 1989. The selection process was based on negative agronomic criteria.

Tests & Trials: Trials for 'Ampera' were conducted in Drummond, New Brunswick in 2007. All entries were planted in single-row plots. Plots consisted of rows 22 meters long with 30 cm in row spacing between plants and spacing between rows of 91 cm. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
