Origin & Breeding History: 'DrisStrawSixtyNine' originated from a cross conducted in 2010 in Ventura County, California, USA. The cross was made between the proprietary female parent '783S 79' and the proprietary male parent '566S 60'. A single plant was selected for asexual propagation by tissue culture and vegetative cuttings in April 2011 in Shasta County, California, USA based on fruit shape, canopy growth, and truss length. Further propagation and testing was conducted from 2011-2016.

Tests & Trials: Trials for 'DrisStrawSixtyNine' were conducted in Chilliwack, British Columbia during the 2021 growing season. The plots were transplanted in the spring of 2020 into plastic mulch with drip irrigation. The plots were arranged in a RCB design. Each variety consisted of 3 replicates per variety with 10 plants per replicate for a total of 30 plants of each variety. Plants were spaced approximately 20 centimetres apart within the row and spaced approximately 3 metres apart between rows. Measured characteristics were based on 10 measurements.
