Origin & Breeding History: The variety 'STP00-10' originated from the open pollination of the variety 'Millennium Russet' with an unknown male parent. The seed was collected in a trial field of 'Millennium Russet' in Florenceville, New Brunswick in 2000. The variety was selected in the field as a seedling in 2001 at Terrance Smith Potato Breeding Farm in Bristol, New Brunswick. A phenotypic recurrent selection technique was utilized in its development. An intensive evaluation process of eight years of trials throughout Canada was used to identify the variety. Characteristics used in the selection process were maturity, yield, disease resistance, processing traits, morphological traits and storage characteristics.
Tests & Trials: Trials for 'STP00-10' 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.
