Genetic variability studies for yield and its components in Brinjal (Solanum melongena L.) Germplasm

The present investigation in brinjal (Solanum melongena L.) was carried out during kharif season of 2019-20 for yield and its components. Analysis of variance indicated highly significant differences among the genotypes for all the traits under study. The estimate of phenotypic coefficient of variation (PCV) was high (>20%) for number of flowers per cluster, fruit length, fruit girth and fruit weight whereas, genotypic coefficient of variation was high (>20%) for fruit length, fruit girth and fruit weight indicates the presence of high variability for these traits and offered better scope for improvement through selection. Low PCV and GCV (<10%) were recorded for days to 50% flowering and days to first pick indicating the narrow genetic base therefore selection for such traits may not give desirable results. High heritability (>60%) coupled with high genetic advance as percent over mean (>20%) was observed for number of secondary branches per plant, number of flowers per cluster, number of clusters per plant, number of fruits per plant, fruit length, fruit girth, fruit weight and fruit yield indicating that these traits were governed by additive genes and there is scope for improving these characters with direct selection.
