Origin & Breeding History: 'Vivaldi' originated from a controlled cross conducted at Fresh Forward Holding B.V. in Elst, Gelderland, The Netherlands. The cross was made in the spring of 2003 between the selection designated 'E1993-053', as the female parent, and the variety 'Sonata', as the male parent. From the resulting progeny, 'Vivaldi' was selected in the summer of 2005 for its fruit quality, fruit production and ease of harvest in Elst, Gelderland, The Netherlands. After its selection, 'Vivaldi' was propagated by cuttings.

Tests & Trials: The comparative trial for 'Vivaldi' was conducted as an outdoor trial during the 2016 and 2017 growing seasons at Webster Farms Limited in Cambridge, Nova Scotia. The plots were planted in mid-June 2016 in a RCB Design. There were 20 plants of each variety divided between four replicates. The plants were spaced 0.51 metres apart within rows spaced 1.52 metres apart. The observations and measurements were taken from 10 plants or 10 parts of plants of each variety in 2017.
