Physical and Chemical Mutagenesis Methods for Development of Insect-Resistant Crop Varieties
Selection of appropriate parents is the first step in breeding for pest resistance. Mutation breeding through physical and chemical mutagens can be resorted to, when the source of resistance is not available. This chapter gives a comprehensive look at the various options for physical and chemical mutagenesis along with their mechanism of action. Steps in mutation breeding for clonally and seed-propagated crops are explained which will enable researchers to take up resistance breeding through mutagenesis.
