Origin & Breeding History: 'Reeves Kingpin' originated from the cross of 'CS7981-7' and 'CF7608-19', made at the University of Maine Potato Breeding Program at the Aroostook Research Farm, Presque Isle, Maine, USA in 1985. The seedling was first selected in the field in 1993.

Tests & Trials: Trials for 'Reeves Kingpin' were conducted in Central Blissville, New Brunswick in 2008. All entries were planted in single-row plots. Plots consisted of rows 22 metres long spaced 91 cm apart with 30 cm in row spacing between plants. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
