Field evaluation of 33 Bambara groundnut lines were carried out to estimate genetic variability, heritability and geneticadvance. One-way analysis of variance (ANOVA) result showed significant differences for 14 of the 17 agronomic traits studied. Theresults on the variance components revealed that phenotypic variance had values (vigour index 2.30, pod length 10.09, seed length 1.64)that were slightly higher than the respective genotypic variance (vigour index 1.68, pod length 9.88, seed length 0.26). Similarly, thevalues (number of branches 41.91, number of nodes 68.72, internode length 59.02) of phenotypic coefficient of variation (PCV) wereslightly higher than the corresponding genotypic coefficient of variation (GCV) (number of branches 40.11, number of nodes 66.98,internode length 57.31), suggesting a substantial genetic variability that can serve as a base for Bambara groundnut improvement. Highestimates of heritability were observed for most characters like number of branches (95.70%), number of nodes (97.46%), internodelength (97.10%), pod length (97.91%), and seed length (93.79%). Likewise, genetic advance values for most traits were high, podlength (201), number of nodes (200), internode length (200), number of branches (197) and seed yield (195), implying thatimprovement of seed yield in Bambara groundnut can be achieved through direct selection.
