The present investigation comprises the data on frequency percentage of chlorophyllmutations in the different doses of gamma rays coupled with EMS in ginger. Different mutationfrequencies and width of mutation spectra were induced under the action of differentconcentrations of the two applied mutagens. The spectrums of chlorophyll mutations (albino,xantha, and chlorina) were observed and grouped. The overall mutation spectrum for gingershowed that xantha occurred with the highest frequency, followed by chlorina and albino. Themutagenic effectiveness decreased with the increase in dose of mutagen for both the mutagenindicating that negative relationship between effectiveness and dose of mutagen. EMS providedmore number of chlorophyll mutants than gamma rays in this investigation.
