A study on ten 'Pinot Gris' cultivar elites was carried on at the Research Station for Viticulture and Enology Murfatlar during the 2021-2022 wine year aimed to authenticate plantation specimens. Ten elites (H1-H10), each with similar growth force, had ten leaves harvested during veraison from the middle part of the shoot. Using a planimeter with 0.1 mm precision, leaf vein length and main angle size were measured. These elites were compared to a control vine from the base plantation. Analysis showed H4, H8, H6, and H9 could be new biotypes for further agrobiological study. H1, H3, and H7 did not differ from the control, suitable for multiplication and maintaining cultivar authenticity. The variation coefficient remained below 30%, ensuring homogeneity and representativeness in the study.
