Origin & Breeding History: The origin of 'Cyrano' is the result of a cross made in 1991 between 'Goldstar' and HO86E423 at HZPC, Metslawier, The Netherlands. The selection criteria included yield, external quality and resistance to diseases and pests.

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.
