The purpose of the present study was to evaluate the effects of mutagens i.e. Ethyl methanesulfonate (EMS) and Sodium azide (SA) on the morphological growth of Okra. Seeds of two Okra varieties Subzpari and Pahuja were first pre-soaked in distilled water and then treated with 0.0 (Control), 0.1, 0.2 and 0.3% Sodium azide (SA) and Ethyl methanesulfonate (EMS) separately. The results showed that the germination rate was significantly decreased with increased lethality (%) and mutation frequency (%) in M1 of both varieties with increasing concentrations of EMS and SA against control. The results showed that different concentrations of EMS and SA affected morphological attributes of both okra varieties as the increase of mutagen concentration showed variable results in M1 generation compared with control, but M2 generation showed useful improvement in various traits. Such as the M2 generation of Subs pari from 0.1% SA treatment showed a decrease in flowering time while an increase in the number of fruits per plant, fruit size, seeds yield (g) per plant and 100 seeds weight.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
