Abstract
Genetic variability is a basic requirement for crop improvement as this provides wider scope for selection. The effectiveness of selection is dependent upon the nature, extent and magnitude of genetic variability present in the material and the extent to which it is heritable. The pesent experiment was conducted to study the variability in F8 advanced breeding lines of groundnut across four environments in the savannah ecological zone of Nigeria. Twenty three advanced breeding lines were evaluated using a randomized complete block design during 2012/13 rain season in each zone. Analysis of variance was carried out for all the traits under study using SAS computer software. The results showed highly significant (P
