Brinjal (Solanum melongena Linn.) is one of the widely used vegetable crops and is popular in many countries viz. Central, South and South-East Asia, some part of Africa and Central America (Gurubban, 1977). It is also known as the aubergine, eggplant, melongene, guinea squash etc. Various data indicate that from the several species that evolved in Africa, one (Solanum incanum), gave rise to a distinct species which spread to South-East Asia as the wild ancestor of Solanum melongena (Lester, 1998).

Taxonomy is the science of identifying (discovering), describing, naming and classifying organisms. It is a complex summing up of knowledge starting with thorough analysis to base the synthesis that will end up in the name of a taxon. Correct identification of biological taxa is a necessary pre-requisite to all other enquiries about the biological world.
