Mutation breeding has been introduced into modern plant breeding in the early 1940's. In spite of pessimistic predictions, the application of experimental mutagenesis has led to encouraging results demonstrating that mutation breeding is a well-functioning method in many crops. So far, more than 500 varieties, developed by means of induced mutations, have been officially released; others have been approved for registration. Many mutants with characters of agronomic interest cannot be utilized directly because of their unsatisfying yielding capacities, or of other negative traits which are partly due to the pleiotropic action of the mutant genes. Sometimes their negative selection value can be overcome by transferring them into the genomes of other varieties. According to experience available, the efficiency of mutant genes can conSiderably vary depending on the genotypic background in which they become effective. The interactions between mutant genes and genotypic back ground cannot be predicted. Therefore, mutants with valuable traits should be crossed with many varieties and strains in order to discern positive and negative interactions. In this way, genotypes can be selected in which the mutant gene is able to express its action without showing negative by-effects. This procedure has been used for about 10 years by combining the methods of mutation and crossbreeding. Mutation breeding is predominantly used in annual diploid and allo polyploid self-fertilizing crops, while it causes much more difficulties in cross-pollinating species.

Mutation means a sudden phenotypic change in a character of an individual, not due to crossing or segregation or an alteration in the macro-molecule of DNA (where it remains open, whether the alteration leads to a change in gene function or not). It also means the augmentation of genetic material through nucleotide or gene copies, through additional individual chromosomes, as well as through the multiplication of whole genomes towards polyploidy. # Plant breeding requires genetic variation of useful traits for crop improvement.Often, however, desired variation is lacking. Mutagenic agents, such as radiation and certain chemicals, then can be used to induce mutations and generate genetic variations from which desired mutants may be selected. Therefore, mutation breeding means: (1) The phenotypic alteration, and (2) The various underlying molecular and numerical changes. But in any case, a mutation has to be phenotypically expressed to be selectable, all other mutations are only of scientific interest. # The present book includes the chapters like: Mutation: General concepts, Mutation: The Molecular Basis, Mutation: Variation in chromosome number and structure, plant breeding using mutations, induced mutation and plant breeding, techniques of mutation breeding plant biotechnology, mutation and breeding, somaclonal and gametoclonal variant selection, techniques of induced mutation, and new cultivars developed by mutation breeding. In the end selected references have been appended.
