The mutant inbred of corn Yuanfu No. 17 and other different mutants with different characters was obtained from Gong No. 17 after the pollen was irradiated by gamma ray. Its genetic variation was identified by using method of electrophoresis in starch gel and of P x Q model of cross. Experimental results showed that variation of esterase isozyme, colour of leaf sheath, were attributed to gene mutation, and estimation of combining ability showed distinguished difference between parent and mutations. The results of experiment have shown that improving varieties will be achieved through inducing gene mutation by irradiation with gamma ray, fast neutron and by treatment with chemical mutagens
