Bambara groundnut (Vigna subterranean) is among the lesser known crops amongst the leguminous species perhaps this obscurity is because of the popularity of known groundnut (Arachis hypogeal) that has similar agronomic behavior as Bambara but it is becoming relevance in African settings based on the nutritional values, lesser agronomic costs (needs no stake), ability of the crop to intercrop with cereals and other major potentials this crop exhibits. Botanical study shows that Bambara groundnut belongs to Faboideae subfamily of the legumes which always have its ripe pods underground.

IITA genebank has the largest Bambara germplasm collection of 1752 accessions from 27 countries across the globe.
