Methods for Inducing Mutations,ency of chlorophyll mutants in the M. generations was used as test for judging the effectiveness of the mutagens used. For the problems dealt with in the present book it is not necessary to discuss these methodological questions in detail. Many information in a summarized form is given in the . (Int

The Selection Value of Mutant Genes,represents a complex phenomenon of mutants and recombinants which is composed of a large number of different traits, most of them having not yet been studied in detail in the mutant material available. All those criteria which influence the competitiveness of the plants directly or indirectly, their

The Utilization of Mutants in Crossbreeding, According to the results available in this field, it is, however, the opinion of many geneticists, that the utilization of useful mutants in crossbreeding programs is more prospective. In this way, negative features of some mutants can be eliminated and only the positive ones are utilized. Moreover
