Origin & Breeding History: 'Preble' was bred and developed in Syracuse, New York as part of a planned breeding program. 'Preble' originated from a hybrid cross conducted in February 2001, between the female parent 'SV2' and the male parent '9970-037'. 'Preble' was selected based on biomass yields, resistance to disease and pests, and agronomic traits for mechanical planting, harvesting, and post-harvest processing.

Tests & Trials: The detailed description of 'Preble' is based on the UPOV report of Technical Examination, application number 2013/0734, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by the Bundessortenamt in Scharnhorst, Germany, between 2014 and 2015.
