Abstract: Eggplant (Solanum melongena L.), having wide variability, offers a good deal of opportunity for genetic improvement. Wide variation occurred for different quantitative traits. Analysis of variance revealed significant variation for all the quantitative characters. High genotypic coefficient of variation (GCV) was observed in fruit length, fruit diameter, number of fruits/plant, fruit weight and marketable yield/plant. The characters fruit length, fruit diameter, fruit weight and number of fruit/plant shows high heritability, along with high genetic advance as percent over mean which indicated inheritance of those characters is controlled mainly by additive genes, and selection based on phenotypic performance may prove useful. Number of branches/plant, fruit diameter and marketable yield/plant had significantly positive genotypic correlations with total yield/plant. Out of ten yield component traits, marketable yield/plant followed by fruit weight and number of fruits/plant exhibited highly positive direct effects on total yield/plant. These traits should be used to improve fruit yield of brinjal.
