Genetic Investigation of Yield and Related Components in Some Landraces of Brinjal (Solanum melongena L.)

Abstract

An experiment was conducted at Shivapuri, Chidambaram, Tamil Nadu, India for estimation of genetic variability parameters. The genetic investigation studies in 46 brinjal genotypes estimated genetic variability parameters namely Phenotypic (PCV) and Genotypic (GCV) coefficient of variation, range, mean, genetic advance and heritability. The ANOVA due to genotypes is found to be significant indicating the genotypes under study are diverse. The PCV for all characters were slightly higher than GCV, indicating the presence of little environmental influence. The high values of heritability and GAM for yield per plant and yield related traits like fruit weight, fruit length, number of fruits per plant and number of fruits per cluster suggest the inclusivity of these genotypes for yield improvement in brinjal. Further, the genotypes could be studied for genetic and specific combining ability, in-order to include valuable landraces in location specific and objective specific breeding programs.
