Origin & Breeding History: 'DrisStrawSeventyTwo' originated from a cross conducted in June 2013 in East Malling, Kent, United Kingdom. The cross was made between the proprietary female parent 'UUK 125-001' and the proprietary male parent 'UUK 143-001'. A single plant was selected for asexual propagation by vegetative cuttings in July 2014 in East Malling, Kent, United Kingdom. Selection criteria was for yield, fruit size, shelf life, and fruit flavour. Further propagation and testing was conducted from 2014 to 2018.

Tests & Trials: Trials for 'DrisStrawSeventyTwo' 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.
