Abstract
The correlation coefficients among nine yield and yield attributing characters with their path
effects towards kernel yield were investigated in F 3 generation for three crosses of groundnut
during Kharif-2009. From association studies, kernel yield was significant and positively
correlated with number of pods per plant, pod yield per plant, shelling percentage and hundred
kernel weight for all the crosses. The path analysis indicated that among the nine traits
studied, pod yield per plant exerted maximum positive direct effect on kernel yield per plant
for all the three crosses. When both direct and indirect positive contributions were
considered, number of pods per plant and pod yield per plant influenced kernel yield per
plant. Thus, on the basis of correlations and direct and indirect effects, number of pods per
plant, pod yield per plant, hundred kernel weight and shelling percentage were proved to be
the outstanding characters influencing kernel yield in groundnut and need to be given
importance in selection to achieve higher kernel yield.
