Origin & Breeding History: 'DrisStrawSixtyFour' originated from a cross conducted in November 2010 in Santa Cruz County, California. The cross was made between the patented female parent 'DrisStrawForty' and the patented male parent 'DrisStrawTwentyThree'. A single plant was selected for asexual propagation via stolons in January 2012 in Hillsborough County, Florida based on yield, plant architecture, plant vigour and health, fruit stem strength, fruit size, fruit shape, flavor, eating quality and shelf-life.

Tests & Trials: The detailed description of 'DrisStrawSixtyFour' is based on the UPOV report of Technical Examination, application number 2019/1423, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted at the Escaroupim Studies Center - Agricultura, Florestas E Desenvolvimento Rural, in Portugal from 2020 to 2021.
