ABSTRACT
Correlation and path co-efficient analysis were carried out for physiological, yield and yield contributing characters in 32 genotypes of groundnut. The genotypic correlation co-efficients were found to be of relatively higher magnitude than the corresponding phenotypic correlation co-efficients indicating strong inherent association between the characters. Pod yield displayed significant positive association with number of primary branches per plant, number of secondary branches per plant, number of pegs per plant, number of mature pods per plant, number of immature pods per plant and harvest index. Path co-efficient analysis revealed high direct effects of these characters on pod yield. Hence, it would be rewarding to give due importance on the selection of these characters for rapid improvement in pod yield of groundnut.
Key words :
Character association, Genotypic & Phenotypic correlation, Groundnut, Path analysis, Yield attributes.
