ABSTRACT

Correlation and path co-efficient analysis were carried out for pod yield and its contributing characters in 168 germplasm lines and five checks of groundnut. Correlation studies indicated that pod yield per plant was significantly and positively associ-ated with harvest index, 100 seed weight, kernel yield per plant, number of mature pods per plant, total number of pods per plant, shelling percentage and number of pegs per plant. Path analysis revealed that kernel yield per plant under organic management and kernel yield per plant and total number of pods per plant under inorganic fertilizer management recorded high positive direct effect on pod yield per plant. Hence, it would be rewarding to give due importance on the selection of these traits for rapid improvement in pod yield of groundnut.
