Studies on character association and path analysis in groundnut (Arachis hypogaea L.)

Abstract

The study was undertaken to estimate the character association, direct and indirect effects by path analysis for pod yield and its components by using 39 groundnut genotypes. The genotypic correlation coefficients were found to be relatively closer to the corresponding phenotypic correlations coefficients, representing strong inherent association between the traits. Pod yield was significant positively correlated with Kernel yield, Shelling percent and hundred kernel weight and significant negative association with day to 50% flowering, days to maturity and dry haulm yield. Path coefficient analysis revealed that the direct positive effect of kernel yield followed by days to maturity.
