Abstract:

An experiment was conducted to study the effectiveness and efficiency of one physical mutagen i.e. gamma rays and two chemical mutagens i.e. ethyl methanesulfonate (EMS) and nitrosoguanidine (NG) in greengram. To study the nature and effect of mutagens in greengram, the percentage of lethality, pollen sterility, frequency of chlorophyll mutations, mutagenic effectiveness, mutagenic efficiency and mutation rates of each mutagen were estimated. The values of mutagenic effectiveness indicated that 30kR in gamma rays, 0.3% in EMS and 0.005% in NG treatment are found most effective than other doses/concentrations. NG exhibited as the most effective mutagen whereas gamma rays found as the most efficient mutagen and comparatively higher in mutation rate than EMS and NG. Among all the mutagenic treatments, the maximum efficiency observed in gamma rays 30KR treatment and the lowest efficiency observed in NG 0.015% treatment based on lethality and pollen sterility. Based on lethality and pollen sterility, the maximum mutation rate among all mutagens was observed in gamma rays treatments followed by EMS.
