Origin & Breeding History: DrisStrawSeventyThree' originated from a cross conducted in August 2013 in Huelva, Spain. The cross was made between the female parent 'DrisStrawThirtyFour' and the proprietary male parent 'VES 030-092'. A single plant was selected for asexual propagation by vegetative cuttings in 2014 in Valladolid, Spain. Selection criteria was for fruit shape, post harvest fruit quality, fruit size, and plant productivity. Further propagation and testing was conducted from 2015 to 2018.

Tests & Trials: Trials for 'DrisStrawSeventyThree' 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.
