Abstract
Mutagenic effectiveness and efficiency of gamma rays, EMS and combined treatments was studied in terms of M2 (progenies) lethality and chlorophyll mutations in two cultivars of soybean (Pusa-16 and PK-1042). In general the frequencies of chlorophyll mutations were high in gamma rays and combined treatments. Four types of mutants viz., albina, xantha, chlorine and viridis were observed in the study. Gamma rays were found to be more effective to induce chlorophyll mutations in both cultivars. PK-1042 cultivar exhibited higher mutagenic efficiency as compared to Pusa-16 in EMS and gamma rays treatment.
Key words: Effectiveness, efficiency, gamma rays, EMS, soybean.
