Origin & Breeding History: 'DrisStrawSixtyEight' originated from a cross conducted in June 2009 in Santa Maria, California, USA. The cross was made between the female parent 'DrisStrawTwentySeven' and the male parent 'DrisStrawThirtyThree'. A single plant was selected for asexual propagation by tissue culture and vegetative cuttings in April 2010 in Shasta County, California, USA based on early and late yield, shipping capacity, fruit size, fruit taste and aroma, and mite and botrytis field tolerance. Further propagation and testing was conducted from 2013-2017.

Tests & Trials: Trials for 'DrisStrawSixtyEight' were conducted in Chilliwack, British Columbia during the 2021 growing season. The plots were transplanted in April 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
