Population structure and genetic variation was estimated for 40 Indian and African finger millet genotypes using 237 random amplified polymorphic DNA (RAPD) and 16 morphological markers revealing differences between African and Indian groups. African genotypes showed 53.59%; 0.17±0.19; 0.27±0.27 compared to 48.10%; 0.15±0.19; 0.24±0.27 polymorphism, Nei's gene diversity and Shannon's Information index, respectively in Indian genotypes. Primers OPM-20, OPW-04, OPX-11 were identified as the most informative primers in terms of high % polymorphism and Nei's gene diversity values. Population structure analysis revealed the existence of two distinct sub-groups, correlated well with primary and secondary centers of finger millet diversity and can be utilized to enhance and widen finger millet germplasm base.
