Abstract

Thirty bunch groundut varieties were evaluated for genetic parameters and degree of association between yield and its components. Number of pods per plant exhibited maximum genotypic and phenotypic co-efficient of variation. 100-pod weight had maxi- mum heritability and genetic advance. Phenotypically, pod yield had positive correla- tion with 100-kernel weight and oil content. Number of pods per plant had negative association with 100-pod weight and 100-kernel weight while shelling out-turn showed a positive correlation with them.
