Abstract :
Seeds of Capsicum annuum L. var. G4 were subjected to different concentrations of methyl methane sulphonate (MMS) and diethyl sulphate (DES). The effects of different mutagenic treatments on meiosis, chiasma frequency, and pollen fertility have been studied in M1 generation. Various types of meiotic aberrations such as univalent, multivalent, stickiness, bridge, laggards, cytomixis etc. were observed in all the treatments. However, the MMS treatments proved to be more effective in inducing meiotic aberrations as compared to DES. Moreover, the frequency of meiotic aberrations was at its maximum at metaphase followed by anaphase and telophase stages.As the concentrations increase, reduction in chiasma frequency and pollen fertility was observed in all the treatments and, MMS again was found to be more effective than DES treatments.
