Origin & Breeding History: 'Pearl' originated from a controlled cross pollination conducted in February and March of 2009 in Oakland, Maryland, USA. The cross was conducted between the varieties 'ZGN-e1', as the female parent, and 'XN-1vf', as the male parent. The resulting seeds were germinated and seedlings were grown in field trials in Cartaya, Huelva, Spain. An individual seedling was selected from the field in Cartaya in March 2011 and coded as DKX-12EF. Selection was based on fruit size, firmness, flavour, colour, appearance and ability to ship and store. The variety was then subsequently named 'Pearl' and put forward for commercialization.

Tests & Trials: The detailed description of 'Pearl' is based on the UPOV report of Technical Examination, application number 2014/2771, purchased from the Community Plant Variety Office, in Angers, France. The trial was conducted by the Bundessortenamt, in Prufstelle Wurzen, Germany, from 2016 to 2017.
