Abstract Grapevine (Vitis vinifera L.) is one of the oldest and most important cultivated fruit crops. The aim of present investigation was to evaluate grape accessions that have been under cultivation in India for a long time. In the current study, ampelographic and fruit character of forty-nine accessions were investigated. A high variability was found in the evaluated grape accessions, and significant differences were found among the studied accessions for the measured parameters. Mature leaf, shoot tip, bunch parameter, berry parameter, total soluble solids (TSS), and total acidity (TA) showed a wide variation. Significant positive correlation found between bunch and berry traits and negative correlation between TSS and TA. Cluster analysis and principal component analyses showed a considerable fruit diversity in the studied grape germplasm. The obtained data revealed phenotypic and genotypic variation within studied grape accessions might be considered as characterizing gene pool and that contributed to the future breeding process of grape.
