Abstract
Chickpea is an important food legume grown worldwide. There is an increasing concern on narrowing of genetic base in most of the grain legumes including chickpea. Mutagenesis using ionizing radiations is one of the many ways of increasing genetic variability. To explore the potential of electron beam irradiation for mutagenesis and to compare it to gamma rays, seeds of a popular chickpea variety ‘Vijay’ were irradiated with four doses (200-500 Grey) of either electron beam or gamma rays. The M1 plants were grown in the field, harvested individually, and sown in the subsequent year to raise M2 plant to row progenies. Chlorophyll and other morphological mutants were identified in the M2 generation. The mutation frequency was found to be more for electron beam irradiation as compared to gamma rays treatments of the same dose.....
