Origin & Breeding History: 'DrisStrawSeven' arose from the cross of the unnamed proprietary variety '77GI' (female parent) by the variety 'Camarillo' (male parent) conducted in June 2002 in Hillsborough County, Florida, USA. In June 2003, 'DrisStrawSeven' was initially selected from the seedling population based on large fruit size and fruiting cycle. It was asexually propagated at Driscoll Nursery in Shasta County, California and underwent further propagation and testing for four years at the nursery in Hillsborough County, Florida, USA.

Tests & Trials: Trials for 'DrisStrawSeven' 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.
