Origin & Breeding History: The origin of 'Juwel' is the result of the cross made in 1994 between 'BS 858-58' as the female parent and 'Flora' as the male parent at the Alexander von Zwehl breeding station in Oberarnbach, Germany. Selection criteria included maturity, yield, disease resistance, processing traits, morphological traits and storage characters.
Tests & Trials: Tests and trials for 'Juwel' 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.
