Origin & Breeding History: The origin of 'Canberra' is the result of the cross made in 1997 between 'Latona' as the female parent and 'Red Scarlett' as the male parent at the HZPC Research & Development Centre in Metslawier, The Netherlands. Selection criteria included internal and external quality, yield and resistances against different diseases and pests.

Tests & Trials: Tests and trials for 'Canberra' were conducted during the 2012 growing season in Drummond, New Brunswick. Each plot per variety consisted of 60 plants grown in a single row with a row length of 18.5 metres and a row spacing of 0.9 metres between rows. Plants were spaced 0.30 metres apart.
