Abstract :
Analysis of variance revealed significant variation among the genotypes for all the character studied. The studies also showed that the PCV were higher than the GCV for all the characters studied indicating the role of environmental variance in the total variance. High heritability coupled with high genetic advance as percent of mean was observed in days to 50% flowering and diameter of pods indicating that these characters are controlled by additive gene effect and phenotypic selection of these characters would be effective for further breeding purpose. Correlation analysis revealed significant positive association with seeds per pod and shelling percentage. The path analysis revealed that seeds per pod contributed maximum positive direct effect on pod yield per plant and also exhibited positive correlation with yield. This shows true relationship between these traits and selection emphasis should be given on seeds per pod.
