In the present investigation, the mutagenic effectiveness and efficiency of different doses of a physical mutagen (gamma rays) were studied in clusterbean (Cyamopsis tetragonoloba (L) Taub) genotypes (viz. GST-15-204, RGC-1066, RCG-1055, RGC-1038. Ten different doses of gamma rays (viz. 5kR, 10kR, 15kR, 20kR, 25kR, 30kR, 35kR, 40kR 45kR and 50kR) were applied to. mutagenised the seeds of cluster bean genotypes. The effectiveness and efficiency was determined by accounting lethality and sterility in M1 generation of mutagenized seeds and frequency and spectrum of chlorophyll mutations in M2 generation. Four types of chlorophyll mutants albino, xantha, chlorina and viridis were screened in M2 generation. It has been observed that the frequency of mutations increased with increasing doses of mutagen. Though the highest mutation frequency was noticed in 50kR dose of gamma rays, the mutagenic effectiveness and efficiency was decreased with increased doses of gamma rays. Thus, the lower doses of mutagen like gamma rays were observed to be more effective and efficient than the higher doses of gamma rays in all four clusterbean genotype.
