Intertrait Associations and Path Analysis Studies in Groundnut (Arachis Hypogaea L.)

The study was undertaken to estimate inter trait associations along with direct and indirect effects by path analysis for dry pod yield and its components in groundnut. Dry pod yield had significant positive association with days to flowering, days to maturity, haulm yield per plant and kernel yield per plant. At genotypic level too these traits had high positive correlation with dry pod yield. Path analysis indicated high positive direct contribution of kernel yield per plant. Days to flowering, days to maturity and haulm yield per plant made indirect contribution to dry pod yield via kernel yield per plant. It was concluded that these traits must be given weightage during selection in the segregating generations for the improvement of dry pod yield in groundnut.
