Origin & Breeding History: The origin of 'Miss Blush' is the result of the cross made in June 1999 between a selection resulting from 'Bildtstar x CD1045-2' as the female parent and an undesignated selection resulting from a self crossing, as the male parent at Dronten, The Netherlands. Selection criteria included maturity, yield, disease resistance, processing traits, morphological traits and storage characters.
Tests & Trials: Tests and trials for 'Miss Blush' 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.
