Mutagenesis occupies a prime position in biological researches. It is the most important method for inducing alterations in qualitative and quantitative characters in a shortest possible time and provides good scope for selection. Scientists are working on different facts to accomplish a significant breakthrough in basic understanding of mutagenesis and also its applied value for the benefits of mankind. The induction of genetic variability becomes the main source of breeding work, thus replacing conventional breeding method which depends on the naturally occurring mechanism of genetic...
