Abstract

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