USE OF PRIMARY AMPELOGRAPHIC DESCRIPTORS IN ESTABLISHING THE SIMILARITY-DIFFERENCE DEGREE BETWEEN VINE VARIETIES WITH DIFFERENT ORIGINS

Vine varieties, no matter which their production direction may be, are characterized by an emphasized morphologic variability, given by their genetics, but also by the fact that these are influenced in a higher or lower degree by climatic and agro-technical factors, thus manifesting differently, according to the crop area. Within this study, it was aimed to morphologically express the 'Pinot noir', 'Pinot blanc', 'Pinot gris', 'Chardonnay', 'Traminer rosé' varieties under the conditions of the experimental field of U.A.S.V.M. Bucharest. The studied varieties show a common lineage and they all show their stressed character of morphological variability. For the ampelographic description, there have been used 37 ampelographic descriptors according to the International Organisation of Vine and Wine (OIV) descriptors as modified by EU project Genres CT96 No81. The achieved results highlight different degrees of similarity of these varieties with the 'Pinot noir' variety, taken as standard, and the variety with the lowest degree of similarity is 'Chardonnay' - with a percentage of only 45.94% compared to the standard.
