Origin & Breeding History: The variety 'Purple Pelisse' originated from a cross between NDOP5847-1 and red bulk pollen, made in Prosser, Washington, USA in 2000. The variety was selected in the field as a seedling in 2001 at Madras, Oregon, USA. A phenotypic recurrent selection technique was utilized in its development. The variety was tested for six years in public and industry trials throughout the western USA. Characteristics evaluated in these trials included maturity, yield, disease resistance, processing traits, morphological traits and storage characters.

Tests & Trials: Trials for 'Purple Pelisse' 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.
