Origin & Breeding History: 'DrisStrawSeventyOne' originated from a cross conducted in December 2011 in Monterey County, California, USA. The cross was made between the proprietary female parent '35T 42' and the proprietary male parent '50T403'. A single plant was selected for asexual propagation by tissue culture and vegetative cuttings in May 2013 in Monterey County, California, USA. Selection criteria was for growth habit, plant health, and fruit appearance and flavour. Further propagation and testing was conducted from 2013 to 2017.

Tests & Trials: Trials for 'DrisStrawSeventyOne' 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.
