Assessment of correlation and path coefficient analysis for pod yield and it’s attributing traits in groundnut (Arachis hypogaea) germplasm

Correlation and path co-efficient analysis were carried out for pod yield and its attributing traits in 105 groundnut germplasm. The pod yield per plant had highly significant and positive correlation at phenotypic level with kernel yield per plant, number of matured pods per plant, harvest index, hundred kernel weight, hundred pod weight, haulm yield per plant, oil content and days to 50 percent flowering. Path analysis revealed that days to maturity, number of matured pods per plant, hundred pod weight, haulm yield per plant, kernel yield per plant and harvest index exhibited positive direct effects on pod yield. Hence, these are most important traits which could be used as selection criteria for effective improvement of pod yield.
