Abstract

The chickpea seeds of variety Vijaya were mutagenized with 0.05%, 0.10% and 0.15% concentrations of EMS and M1 population was raised. After studying the various biological parameters from M1 generation, the M1 generation was harvested. The seeds of M1 generation were sown and M2 generation was raised. The entire M2 generation was thoroughly screened for chlorophyll mutants. The frequency and spectrum of chlorophyll mutants was calculated. The increasing trend of chlorophyll mutation frequency with increasing concentration of EMS was recorded. Highest frequency at 0.15% concentration was recorded. Broad spectrum of chlorophyll mutants was recorded. Various chlorophyll mutants recorded were xantha, chlorina and viridis.
