Abstract	Upon publication of the classic paper of muller (1927) and Stadler (1928), many researchers started to use various chemical and physical mutagen to implant the large step mutations in array of plant systems. By this methodology a variety of plant strain had been produced which become important and worthful asset in number of plants which can be used for improvement of crop plants. Niger is an important oilseed crop in India with many surprising nutritional values, in addition it can be cultivated in very less agricultural inputs. it provides a good commercial support to farmers. India is the chief producer of Niger seed having second and fourth rank in world for its average and annual production respectively. But now days due to low production in relation to required production the cultivation rate of Niger is getting declining. Mutation breeding is the important tool to induce mutation and produce a good strain of economical important strains of Niger. During present study a broad range of viable morphological and physiological mutants were observed in M1 generation of Niger [Guizotia abyssinica (L.f.) Cass.] raised from seeds treated with different concentrations of Sodium Azide and Ethyl Methane Sulfonate. Mutation obtained includes high seed germination percentage, chlorophyll deficiency sectors, leaf morphological, earliness, flower morphology and life cycle duration. The true breeding mutants were compared with its parent (Control) to assess its superiority. Mutant Shows higher germination percentage than control. mutation induced different chlorophyll deficiency sectors (Chlorina, Albina and xantha), changes in leaf morphology and flower morphology. The early mutant lines matured 10 days earlier than the parent variety
