Genetic variability, heritability, genetic advance, and correlation for different characters were studied in five grape genotypes during 2015-16 to identify accessions with useful traits for improvement programme. The study indicated existence of considerable amount of genetic variability for all the traits and demonstrates the usefulness of the genetic material as a donor of important genes for grapevine improvement. The maximum phenotypic and genotypic coefficient (PCV and GCV) was observed for number of bunch. High estimates of heritability (broad sense,) and genetic advance were observed for most of traits indicated that these are under control of additive gene action. Pearson correlation indicated fruit yield per vine showed highly significant correlation between number of bunch and significant correlation with pruning weight and weight of bunch. Number of berries per bunch was found significantly correlated with weight of bunch, days taken to 50% flowering, days taken to 50% fruit set and number of bunch. Hence, purposeful and balanced selection based on these traits would be more rewarding for improvement of grape.
