Origin & Breeding History: The variety 'Tebina' originated from a cross between 86-26-02 and 'Agria', made in the Netherlands in 1993. The variety was selected in the field as a seedling in 1994 at Wieringermeer, the Netherlands. A phenotypic recurrent selection technique was utilized in its development. An intensive selection process of more than six years was used to identify the variety. Selection criteria included maturity, yield, disease resistance, processing traits, morphological traits and storage characters.

Tests & Trials: Trials for 'Tebina' were conducted during the summer of 2010 in Drummond, New Brunswick. Plots consisted of one row with a row length of 18.5 meters and a row spacing of 90 cm. Plants were spaced 30 cm apart within the row. There were 60 plants per variety in the trial. Measured characteristics were based on ten measurements.
