Vegetables play a pivotal role in our diet as they are the main source of some important supplements, especially vitamins and minerals. Most of the fruits of genus Solanum are used as vegetables and the eggplant is one of the most common and popular vegetables grown throughout the World. Mutation breeding seems to be a handy tool for improving the quantitative and qualitative characters in various crop plants. Therefore, physical and chemical mutagens are being used in genetic improvement programmes of different plant species. The main purpose to publish this work is to acquaint those who are pursuing research in the field of cytogenetics and mutation breeding or M.Sc. (Botany/Cytogenetics and Plant Breeding). I am thankful to LAP LAMBERT Academic Publishing GmbH & Co. KG, Germany to approach me for publishing my research work.
