Evaluation of the ampelographic characteristics of the new accessions introduced in grapevine germplasm collection (Vitis vinifera L.)

Abstract

The characterization of 22 grapevine accessions (Vitis vinifera L.), considered old, autochthonous and in danger for extinction, was performed using 49 OIV descriptors. The evaluation of the ampelographic descriptors for the young shoot, the young and mature leaf, the bunch, as well as some production and quality parameters, highlighted the diversity of the epigenetic characteristics of the newly introduced accessions into collection. The morphological description revealed the main features of each accession and the applied statistical approaches confirmed the possible relatedness among studied genotypes linked to all 49 descriptors.
