Identification of plants with higher seed yield and yield contributing characters are the major aspects in crop development programmes.For this purpose a research was carried out by using EMS for inducing mutations in blackgram accession IC- 436524.This experiment was performed by treating the blackgram seeds atdifferent concentrations of EMS viz; 0.2, 0.3, 0.4, 0.5 percent and control(EMS untreated) and T-9(as check) and grown to develop M1 generation seeds.Seeds ofblackgram mutantsfrom each treated mutants from each concentration collected and raised for M2 generation to determine the mutations inherited from M1 generation mutants to its next generation. The observation was recorded for higher seed yield and its contributing characters from M2 generation mutants.Our results demonstrated a large amount of genetic diversity among the black gram mutants due to the EMS treatments for all characteristics during M1 and M2 generation. ANOVA data also revealed there was a significant variability among the treated mutants in studied characters. From the data it was revealed that high yielding blackgram mutants of M1 generation has showed similar trend in higher yielding during M2 generation also.Compared with other treated mutants0.2% treated mutants had higher yield and more significant variability were observed in other selected characters.According to the findings as a whole, the chosen black gram mutant that was grown in an environment with 0.2% EMS concentration demonstrated a significantly better seed output when compared from other mutants and the untreated black gram genotype and T9. It's possible that the mutant will prove valuable in the process of breeding higher-yielding genotypes for future agricultural improvements and for the benefit of farmers.
