Origin & Breeding History: 'DrisStrawThirtyTwo' arose from the cross of the unnamed proprietary variety '89J167' (female parent) by another unnamed proprietary variety '283M52' (male parent) conducted in April 2005 in Kent, England, United Kingdom. In June 2007, 'DrisStrawThirtyTwo' was initially selected from the seedling population based on yield, fruit size, fruit shape, flavour, shelf life and fruiting season. It was asexually propagated and underwent further propagation and testing from 2007 to 2012 in Kent, England, United Kingdom.

Tests & Trials: Trials for 'DrisStrawThirtyTwo' were conducted in Chilliwack, British Columbia during the 2014 growing season. The plots were planted in the spring of 2013 in a randomized complete block design (RCBD). Each variety consisted of 3 replicates/variety with 5 plants per replicate (for a total of 15 plants of each variety). Plants were spaced approximately 30 centimetres between plants in the row and spaced approximately 2.5 metres apart between rows. Measured characteristics were based on 10 measurements.
