A Field experiment with 30 advanced breeding lines of groundnut was carried out for assessment of genetic variance, heritability (broad sense) and genetic advance as per cent of mean for 17 metric traits. The analysis of variance revealed the existence of highly significant differences among the entries for all the characters studied. The phenotypic coefficient of variation (PCV) was greater than genotypic coefficient of variation (GCV) for all the traits studied implying that these characters were highly influenced by the environmental effects. High PCV and GCV values (>20%) was recorded for Pod yield plant-1, Kernel yield plant-1, dry haulms yield plant-1 and number of mature pods plant-1. High heritability (> 60%) coupled with high genetic advance as per cent of mean was registered for plant height, hundred pod weight, kernel yield plant-1, dry haulms yield plant-1, number of primary branches plant-1, number of mature pods plant-1, harvest index and pod yield plant-1 indicating that these characters were governed by additive gene effects and could be chosen as selection criteria for formulating breeding strategies in groundnut.
