英文摘要：

Molecular marker as a new type of genetic marker has been gradually used in flowering Chinese cabbage in recent years. The principles and characteristics were introduced for several molecular markers utilized in the study of flowering Chinese cabbage. The progresses and achievements have been reviewed on genetic diversity analysis, fingerprinting and identification of hybrids, genetic linkage map and QTL detection. The problems presented and the perspectives in the use of molecular markers in fiowerin~ Chinese cabbage were analyzed and discussed.
