Abstract Genotoxic effects of a heavy metal, i.e. lead (Pb), on cyto-morphological parameters of chilli were investigated. Seeds were treated with five different concentrations (20, 40, 60, 80, 100ppm) of this heavy metal. The higher concentrations of lead nitrate significantly reduced plant height, pollen fertility and yield and caused variations in the plant at the seedling and mature stages. In addition, lead affected the pairing of homologous chromosomes and spindle formation: as the concentration of lead increases chromosomal abnormalities also significantly increase but chiasma frequency reduced. On the basis of these results, it was concluded that lower concentrations of metal did not significantly affect the cyto-morphology of Capsicum, while higher concentrations of lead nitrate were found to be more mutagenic and genotoxic.
