Abstract: Mutagenic effectiveness and efficiency of individual treatments of EMS and gamma rays were assessed in pigeonpea genotypes, ICPL-87 and BSMR-736. The experiment included total 8 mutagenic treatments (4 for each individual treatment of EMS and gamma rays) per genotype having control one, selected on the basis of their LD50 values. In comparisons of both genotypes, BSMR-736 observed higher rate of mutation frequency than genotype ICPL-87. Effectiveness and efficiency were calculated on the basis of Plant survival and chlorophyll mutation frequency of M2 generation. Mutagenic effectiveness decreased with increased in dose / concentration of mutagen. Where as in mutagenic efficiency the data showed that no specific pattern is followed but variation in mutagenic efficiency was recorded in all treatment.
