Origin & Breeding History: The variety 'Alpine Russet' originated from a cross between A83043-12 and A85103-3, made in Aberdeen, Idaho, USA in 1993. The variety was selected in the field as a seedling in 1994 at Aberdeen, Idaho. A phenotypic recurrent selection technique was utilized in its development. The variety was evaluated for 13 years in public and industry trials throughout the western United States. Selection criteria included maturity, yield, disease resistance, processing traits, morphological traits and storage characteristics.

Tests & Trials: Trials for 'Alpine Russet' were conducted during the summer of 2010 in Drummond, New Brunswick. Plots consisted of one row with a row length of 18.5 meters and a row spacing of 90 cm. Plants were spaced 30 cm apart within the row. There were 60 plants per variety in the trial. Measured characteristics were based on ten measurements.
