Twenty tomato genotypes were evaluated to variability, heritability and genetic advance in yield and genetic advance in yield and quality characters at Vegetable Research Farm, Department of Horticulture, SHUATS, Allahabad. A high analysis of variance revealed significant differences among germplasm for all the traits studies, suggesting sufficient variability for yield and quality characters. The overall values of PCV were higher than those of GCV. Higher magnitude of GCV and PCV, respectively were recorded in (28.21-42.89) acidity followed by (28.04-40.51) TLCV. High values of GCV are an indication of high genetic variability among the germplasm and thus the scope for improvement of these characters through simple selection would be better. In present study, all the characters showed high heritability the magnitude of heritability ranged from 95 % to 90% indicating that there traits are controlled by additive gene action which is very useful in standard selection. The traits like fruit weight, locules/ fruit, TSS, with high GCV, PCV, heritability and genetic advance as percentage of mean, indicating that these characters are under additive gene effects and more reliable for effective selection.
