ABSTRACT

High estimates of PCV, GCV, heritability (broad sense) and genetic advance as percentage
of mean (GAM) were observed for late leaf spot disease severity, reducing sugar, kernel yield per
plant and pod yield per plant. It indicates the role of additive gene action and hence the usefulness
of phenotypic selection for bringing possible improvement. Pod yield showed positive significant
association with days to 50 per cent flowering, days to maturity, kernel yield, test weight and oil
content. The path analysis revealed that high positive direct effect of kernel yield exerted on
pod yield as well as oil content, strong mature kernel, days to 50 per cent flowering, test weight,
days to maturity, and non reducing sugar through kernel yield. Therefore, it would be rewarding
to lay due emphasis on the selection of these characters for rapid improvement in pod yield.
