We carried out irradiation of kanamycin strain with fast neutron and high energy electron for many times. Our practice proved, when the selected mutagenic doses were suitable, for example, 0.10~0.20 kGy for high energy electron and 1~8×10,12, No. of neutron/cm,2, for fast neutron, there were more high mutagenic effects. Besides the suitable mutagenic dosess, the mutagenic effects were in connection with strain sensitivity, irradiation method, selection condition etc. By electron irradiation mutagenic treatment of kanamycin strain, a new kind strain was obtained. Its potency of shak bottle has been increased 10.34~30.8% and the production yield has been increased 4.07~5.23%.
