Abstract：Strong heterosis on yield，quality，disease resistance and stress tolerance is displayed in cabbage（Brassica oleracea L. var. capitata L.）．It is an important approach for heterosis utilization to use male sterileline to produce hybrid seed．In recent years，great progress has been made in studying cabbage male sterility．This paper reviews the types of cabbage male sterility line，its genetic characteristics，and achievements gained in studying its cytology，physiology，biochemistry and molecular biology．The paper also introduces the selective breeding of cabbage male sterile line，and its application．At the same time，the paper analyzes the existing problems and prospects the future for cabbage male sterility line application．
