  The common name “Eggplant” is given to vegetables of several Solanum L. species that are important for human diet and health. The taxonomy and phylogenetic relationships among these taxa are currently unclear due to its large size and tropical center of diversity. This study assessed the genetic diversity in forty nine eggplant and related Solanum species’ genetic resources in Southern Nigeria using one nuclear (ITS) and two chloroplast genes. Analysis of DNA sequence data from the three regions (ITS, trnl C-trnl D and trnl E-trnl F) gave a high level of genetic variability (polymorphism) among the samples studied. A bootstrap value of 100 was observed between S. macrocarpon L. and S. torvum Sw. and between S. macranthum A. Rich. and S. indicum L., closely followed by a value of 99 between S. aethiopicum L. and S. dasyphyllum Schum. and Thonn. All these are indications of a close relationship between these species and a possibility of a common ancestor is strongly proposed. Solanum torvum was often separated out from S. melongena and even where they grouped together they have a low bootstrap value of 3 which is an indication of distant relatedness. The high level of intra and inter specific variations displayed within eggplant accessions and between its relatives as reported in this study could be effectively used in genetic improvement of cultivated eggplant varieties as well as in situ and ex situ conservation.
