Origin & Breeding History: The variety 'Voltis' (INRA-Col-2011G) originated from a controlled cross conducted in June 2002 by the Institut national de la recherche pour l'agriculture, l'aliment et l'environnement (INRAE-ResDur program) in Siebeldingen, Germany between the female parent variety 'Villaris' (Gf 84-21-9) and the male parent 'INRA_3159-2-12'. In 2017, the variety 'Voltis' was selected based on its resistance to downy mildew and powdery mildew as well as its ability to produce wine quality grapes.

Tests & Trials: The detailed description of 'Voltis' is based on the UPOV report of Technical Examination, application number 20172246, purchased from the Groupe d'étude et de contrôle des variétés et des semences (GEVES) in Beaucouzé, France. The trials were conducted by GEVES at the Institut national de la recherche pour l'agriculture, l'aliment et l'environnement (INRAE) in Beaucouzé, France from 2016 to 2018.
