Abstract
Eighty groundnut varieties were raised in a randomised block design with three
replications in upland during kharif. Pod yield and 17 characters were studied. Correlation
coefficients at the genotypic and phenotypic levels were computed between pod yield and
other characters and among themselves. Path analysis for dry pod yield was done
considering eight important component characters.
Dry pod yield was highly correlated positively with fresh weight of pods, haulms yield,
number of mature pods, number of immature pods, duration upto maturity and 100 pod
weight at the genotypic level. Negative significant correlation was seen for pod yield with
plant height at the 50th day, height of main shoot and length of top. Fresh weight of pods
had the highest positive direct effect followed by 100 pod weight, haulms yield and number
of mature pods whereas length of top, number of flowers, number of basal primary branches
and number of leaves exerted negative direct effect to dry pod yield in that order.
