Origin & Breeding History: The origin of 'Daifla' (clone number G93TT018008) is the result of the cross made in 1992 between 'Sylvia' and 'Cara' in Châteauneuf-du-Faou, France. Selection criteria included appearance, yield, agronomic traits, dry matter content, pest resistance, cooking and frying quality, and storability.

Tests & Trials: Tests and trials for 'Daifla' 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.
