Origin & Breeding History: 'CNJ99-52-15' originated from the cross made in 1999 at Rutgers University in Chatsworth, New Jersey, USA between '#35', as the female parent, and 'NJS98-34', as the male parent. A single plant was initially selected from 112 progenies for its yield potential, time of fruit ripening, berry size, shape and colour. In 2007, 'CNJ99-52-15' was selected and planted in replicated variety trials in Oregon, Washington and Wisconsin, USA for additional evaluation. Final advancement of 'CNJ99-52-15' was based on yield and time of fruit ripening.
Tests & Trials: The comparative trial for 'CNJ99-52-15' was conducted during the 2019 growing season at the British Columbia Cranberry Growers Association Research Farm in Delta, British Columbia. In 2017, the trial was planted with 8 plots of 6 plants per plot of each variety for a total of 48 plants per variety. Plots were arranged in a RCB Design, with 8 replications. At the time of planting, there was a spacing of approximately 0.9 metres between plots and a spacing of approximately 0.3 metres between plants. Observations were taken on 20 plants or parts of plants of each variety. Measurements were taken on a minimum of 58 berries of each variety.
