Four elite clonal accessions of Vitis vinifera L., Chasselas doré variety were identified in a very old plantation, of 110 years, located in Valea Cãlugãreascã, on the St. Nicolas Monastery vineyard. The vines, grafted on the SO4 (Selection Oppenheim 4) rootstock, were planted in 2007 in the germplasm collection belonging to the Research and Development Institute for Viticulture and Enology, Valea Cãlugãreascã. The present study aimed to evaluate these elite clonal accessions from ampelographic point of view, in comparison with Chasselas doré variety. Ampelographic characterization of genotypes was performed according to the descriptors ampelographic methodology, based on the specifications made in the OIV Descriptor List for Grape Varieties and Vitis species, Second Edition (2009). The shoot tips descriptions were made when they were approximately 10 to 30 cm in height and, in this stage, also, the first four distal leaves of young leaves were evaluated. Mature leaf descriptions were carried out between berry set and veraison. The clusters and berry characteristics were evaluated at maturity and woody shoots were analyzed after fall of the leaves. Ampelographic characterization was performed based on 59 descriptors, of which 43 for morphological characters and 16 for agro-biological attributes.
