Seeds of Capsicum annuum L. cv. Pusa jwala and G4 were treated with varying concentrations of methyl methane sulphonate (MMS), and the effect of various concentrations of MMS on each stage of meiosis has been studied in M1 generation. Various types of meiotic abnormalities and reduction in chiasma frequency were observed in treated populations. However, MMS treatment were found to be more effective in inducing meiotic abnormalities and reduction in chiasma frequency in Pusa jwala as compared to G4. Moreover, a co-linear relationship between increasing concentrations of MMS and reduction in chiasma frequency was also observed. Taking the percentage of meiotic abnormalities and reduction in chiasma frequency as an index of sensitivity of genotype to MMS, Pusa jwala was found to be more sensitive than G4.
