Evaluation on genetic parameters, interrelationships and path analysis for yield attributes in Brinjal

Abstract

Genetic parameters in terms of heritability, genetic advances, correlation and path coefficient, were estimated for yield and related traits in 16 genotypes of brinjal. The highest GCV was recorded in number of flowers per plant, fruit yield per plant, yield per plot, yield per hectare, average weight of fruits. High heritability coupled with high Genetic Advance were observed for fruit weight, fruit yield per plant, leaves per plant, fruit length, yield per plot, yield per hectare and total reducing sugar indicating that the characters are governed by additive gene action. Correlation and path coefficient (genotypic and phenotypic) revealed that the direct contribution of fruit yield per plant, fruit yield per hectare, fruit weight, number of fruits per plant, and number of flowers per plant was of higher magnitude on fruit yield. These traits play a major role and must be considered in selection program for the improvement of the yield potential of brinjal.
