Mutation breeding is one of the innovative methods in plant
breeding. Hugo de Vries introduced the term mutation in the late
19th century. Since the induction of artificial transmutation of
gene by X-rays on Drosophila by Muller in 1927, the field of
mutation breeding has gained improvement. Cowpea is an important
food legume of the tropics and subtropics.Improvement of cowpea by
conventional breeding techniques is time taking and involves
constraints such as small flower, difficult crossing, poor seed
setting and less number of seeds per pod. Mutation breeding in
recent times as an effective tool for crop improvement and an
efficient means supplementing existing germplasm for cultivar
improvement in breeding programs. Cowpea has immense scope for
genetic improvement for various qualitative and quantitative
characters besides widening the genetic base through induced
mutagenesis. This book will be definitely helpful for researchers,
teachers as well as postgraduate students in standardizing the
studies on mutation breeding in cowpea. This book deals with the
study of induced genetic variability through gamma rays and EMS in
two distinct varieties.
