Origin & Breeding History: 'DrisStrawFiftyOne' originated from a cross conducted on December 7, 2010 in Hillsborough Country, Florida, USA. The cross was made between the proprietary female parent designated '166T218' and the proprietary male parent variety 'DrisStrawForty'. A single plant was selected for asexual propagation by tissue culture and vegetative cuttings in February 2012 in Shasta County, California, USA based on yield, rain tolerance, fruit size and fruit flavour. Further propagation and testing was conducted in Huelva, Spain from 2015 to 2016.
Tests & Trials: The detailed description of 'DrisStrawFiftyOne' is based on the UPOV report of Technical Examination, application number 2017/1982, purchased from the Community Plant Variety Office, in Angers, France. The trials were conducted at the Escaroupim Studies Center - Ministry of Agriculture, Forestry and Rural Development, in Portugal from 2019 to 2020.
