Origin & Breeding History: 'Jive' 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 2004 between a selection designated 'E1998-142', as the female parent, and a selection designated 'E1997-054', as the male parent. From the resulting progeny, 'Jive' was selected in the summer of 2006 in Elst, Gelderland, for its fruit quality, fruit production, ease of harvest and disease resistance. 'Jive' is propagated by cuttings.

Tests & Trials: The comparative trial for 'Jive' 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 the rows that were spaced 1.52 metres apart. The observations and measurements were taken from 10 plants or 10 parts of plants of each variety in 2017.
