Among the macro-mutants, fruit mutants (shape,
size, high chlorophyll content, etc.) were more
frequently occurring followed by leaf mutants. Higher
doses of gamma radiation produced more non-viable
chlorophyll deficient mutants whereas EMS at higher
concentration produced comparatively lesser in number
and in combination treatments, occurrence of nonviable
chlorophyll deficient mutants increased with the
increase in dosage of gamma rays. It was clearly
evident that the physical and chemical mutagens
induced different mutation spectrum and the type of
mutant depended not only on the type of mutagen but
also on the genotype used as recorded in several earlier
studies
