Homogenized prothallus of 6 species (Cyrtomium falcatum, Cyrtomium caryoptideum var. coreanum, Dryopteris varia, Asplenium incisum, Camptosous sibiricus and Phyllitis scolopendrium) were treated with gamma radiation or by chemical mutagenesis with EMS, NMU, $NaN_3$ and colchicine to assess their sensitivities for each treatments and also with the aim of inducing mutations. Generally, decrease of proliferation ratio was dose-dependent and time-dependent. Based on proliferation ratio, optimum dose of gamma irradiation was $5{sim}10krad$ except in D. varia with 20krad. Optimum condition of EMS treatment was considered as 50mM for 3h and for NMU as $5{sim}10mM;for;1{sim}3h$. Optimum condition of $NaN_3$ treatment was considered as $0.5{sim}1mM;for;1{sim}3h$. For colchicine, there were significant differences between species as to the proliferation ratios of prothallus for each treatment.
