ABSTRACT
One hundred and sixty eight germplasm lines and five checks of groundnut were used to study the correlation and path coefficient analysis for yield and yield contributing characters. Correlation studies revealed that kernel yield per plant exhibited highly significant and positive relationship with pod yield per plant followed by number of pods per plant, number of mature pods per plant, harvest index , 100 kernel weight, number of pegs per plant, shelling percentage, number of immature pods per plant, plant height and number of primary branches per plant. Path coefficient analysis indicated that that the number of pods per plant and kernel yield per plant exhibited very high positive direct effects on pod yield per plant. Thus, these characters turned-out to be the major components of pod yield in groundnut.
Key words :
Correlation, Groundnut germplasm, Path coefficient analysis, Yield attributes.
