The goal of this study was to learn more about the nature and extent of genetic diversity, heritability, and genetic progress in cherry tomatoes for various growth, yield, and quality traits. Ten diverse lines of cherry tomato were crossed in diallel fashion (excluding reciprocals) and evaluated for genetic variability studies in open field conditions. The experimental findings revealed that the phenotypic variation and the genotypic variation were equal in magnitude for all the traits indicating less influence of environment on all these traits. High PCV, GCV, and genetic advance as percent mean was observed for several fruits plant-1, average fruit weight (g), fruit yield hectare-1 (q), reducing sugar (%), non-reducing sugar (%), total sugars (%), titratable acidity (%) and ascorbic acid content (mg100g-1), indicating the additive genetic effect. Phenotypic selection for their improvement could be achieved by simple selection.
