Origin & Breeding History: The variety 'Actrice' originated from a cross made in 1999 between 'Denise' as the female parent and 'Agata' as the male parent in Langeloo, The Netherlands. Seed from the cross were sown in a greenhouse in 2000. The resulting tubers were harvested and planted in the field at Langeloo in the spring of 2001. One of the selected progeny was given the designation 'Actrice'. Selection criteria were negative mass selection for agronomic characteristics and resistance for various diseases.

Tests & Trials: The comparative trial for 'Actrice' was conducted during the growing season of 2014 in Drummond, New Brunswick. The trial consisted of a single row with 60 plants spaced 0.3 metres apart for each variety. The distance between rows within the trial was 0.9 metres. Observations and measurements were taken from 10 plants of each variety. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
