The present investigation was undertaken in 110 mung bean genotypes in alpha lattice design in two replications to estimate the correlation coefficients, direct and indirect effects of various yield contributing traits on grain yield for 18 quantitative traits and nine screening traits against bruchids. The correlation coefficient analysis revealed that single plant yield showed high significant positive correlation with number of pods per plant, followed by number of clusters per plant and hundred seed weight. Path analysis showed that days to 50 per cent flowering and number of pods per plant showed high positive direct effect on single plant yield. The bruchid bioassay resulted in the identification of 12 genotypes with complete resistance to bruchids and all the characters showed high significant positive correlation with each other except for number of eggs laid. Hence, the resistant genotypes identified in this study can be used in resistance breeding programme for bruchids. |
