Mutagenesis techniques even the newer ones have resulted in many impressive mutant varieties. The number of such varieties is high across plant species. This book provide details of mutagenesis for crop improvement in vegetables. Emphasis is given on induced mutation breeding, morphological variation, agronomic characters and biochemical investigation of viable mutants in vegetable crops. This book gives an over all glimps of how mutagenesis techniques can be successful for the improvement of vegetable crops. It is hoped that this book will be of great value to students, teachers and researchers in vegetable science, plant breeding as well as reader interested in plant breeding and crop improvement.
