Fifty Arachis genotypes belonging to different botanical types viz., spanish bunch, virginia bunch, valencia, peruviana and aequatoriana were evaluated for 28 quantitative characters to study the genetic variability parameters, correlation coefficient and path analysis.. Analysis of variance indicated highly significant differences among genotypes for all the traits. In the present study high magnitude of genetic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) and high broad sense heritability was observed for 19 characters out of 28 characters. This indicated that these traits were less influenced by the environment and can be improved by simple selection procedure. High genetic advance as percentage of mean was observed for 16 out of 28 characters, which indicate the necessity of utilising these traits for crop improvement for groundnut. From the path analysis study, it was observed that, during kharif season days to maturity had the highest and positive direct effect on kernel yield/plant, while during summer pod yield/plant had the highest and positive direct effect on kernel yield/plant.
