Origin & Breeding History: The origin of 'Savanna' is the result of the cross made in 1993 between 'Famosa' and 'Atlantic' at the Teagasc Oak Park Research Centre, Carlow, Co. Carlow, Ireland. The selection criteria included earliness, skin finish quality, disease resistance, yield and taste.
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.
