As regards MNNG, no mutant plants were obtained
at all concentrations even after 10-weeks (Table 4).
MNNG is a potent mutant and has ability to induced
severe chromosome damage (Francis et al., 1989).
MNNG is used as a tool to isolate morphological mutants
or mutants with variations in calli components-pigments
or proteins. Levy & Ashri (1974) reported the differential
physiological sensitivity of peanut varieties to seed
treatment with sodium azide, ethidium bromide and
MNNG, they found significant interaction between two
varieties
