In order to prove the hypothesis of existing synonymies, ampelographic comparisons were carried out with 7 Spanish cultivars and 13 Portuguese cultivars. Mature leaves were selected and ampelographic characteristics proposed by the OIV for the description of the vine cultivars were measured. The basic parameters for the reconstruction of the mean leaf were recorded. Five synonymies were confirmed after analyzing the data of the different cultivars. A doubtful synonymy was detected in two other cultivars. The remaining cultivars were clearly distinguished. ER -
