BERRY SKIN: yellow green (without bloom), thin
BERRY FLESH: moderately firm, absent or very weak intensity of anthocyanin colouration
Origin & Breeding History: 'Sauvignon Kretos' originated from a controlled cross conducted between the female parent variety 'Sauvignon' and the male parent variety '20/3' made by the University of Udine and the Institute for Applied Genomics in Udine, Friuli Venezia Giulia Region of Italy in June 2002. The controlled cross was conducted using cluster isolation and flower emasculation in the seed parent and cluster isolation in the pollen donor prior to flowering. The first asexual multiplication occurred in 2005. The resulting seedling was selected at the Servadei experimental farm in Udine, Italy based on resistance to mildew, tolerance to Oidium, medium vigour, chemical composition of the berries, wine quality and grafting affinity. 'Sauvignon Kretos' was selected and designated in 2010. The genetic identity of the seedling was verified by DNA microsatellite markers. From 2011 to 2013, the variety was evaluated in production plots of 25 or 100 individuals in two ecologically different sites, Udine and Fossalon Grado, on rootstocks 1103 Paulsen and Kober 5BB.
Tests & Trials: The detailed description of 'Sauvignon Kretos' is based on the UPOV report of Technical Examination, application number 20150368, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted at the Bundessortenamt in Hannover, Germany from 2017 to 2018.
