Origin & Breeding History: The origin of 'Saphire' is the result of the cross made in 1991 between 'Bydand' and 'Caesar' at the Van Rijn-KWS B. V., breeding station in Emmeloord, The Netherlands. Selection criteria included maturity, yield, disease resistance, processing traits, morphological traits and storage characteristics.
Tests & Trials: Tests and trials were conducted during the 2011 growing season in Drummond, New Brunswick. Plots consisted of 60 plants grown in a single row with a row length of 18.5 meters and a row spacing of 0.9 meters.
