Abstract: In recent years, the intermediate energy heavy ion biology has been concerned rarely comparing to that of the lowenergy ions. In this paper, we summarized the advantage of a new mutation breeding method mediated by intermediate energy heavy ion irradiations. Meanwhile, the present state of this mutation technique in applications of the breeding in grain crops, cash crops and model plants were introduced. And the preview of the heavy ion irradiations in genetransfer, molecular marker assisted selection and spaceflight mutation breeding operations were also presented.
