摘要:Present experiment was design to investigate the effect of methyl methane sulphonate and sodium azide on Trigonella foenum-graecum L. treated with different concentrations (0.01, 0.02, 0.03, 0.04, and 0.05%). The results indicate that there was a direct correlation between increasing concentrations of mutagens and parameters studied. Although meiotic abnormalities, pollen fertility and chiasma frequency showed continuous decreasing trend with the increasing concentrations of both the mutagens but the maximum decline was observed at the higher concentration (0.05%) of MMS and lest was at lowest concentration (0.01%) of SA. However, MMS was found to be more effective in inducing meiotic abnormalities, reduction in chiasma frequency and decrease in pollen fertility as compared to SA. Further, a negative relationship between increasing concentrations of mutagen and reduction in chiasma frequency in treated population was also observed.
