Abstract: Randomly amplified polymorphic DNA(RAPD)markers were applied to distinguish purity of commercial F1-hybrid seeds of Chinese cabbage. DNA from two F1-hybrid cultivars, Beijing No.57 and Beijing No.106, and their parental lines were screening with 50 primers. Primer OPE-20 generated in F1-hybrid Beijing No.57 specific RAPD markers. Primer OPH-06 and OPH-07 generated in F1-hybrid Beijing No.106 specific RAPD markers. These markers enabled a clear distinction to be made between F1-hybrids and their parental lines. These primers were used in purity control of hybrid seed production of Beijing No.57 and Beijing No.106 . This result indicated the practical usefulness of RAPD markers in commercial hybrid seeds purity tests of Chinese cabbage.

Key words: Chinese cabbage, RAPD marker, Hybrid purity
