Abstract: The silver-stained AFLP analysis was employed to analyse the DNA fingerprints of four cultivars of Meiren Mei Form , and a wild species , a Pink Double Form and seven relatives. For 420 loci 6 300 bandings was
capable of producing sharp fingerprint patterns with the primer combinations of E-ACT/M-CAT , E-GA/M-CTC , E-ACT/M-CCA , E-ACT/M-CAC. NTSYSpc 2. 1 was used to SAHN Clustering of UPGMA and according to DICE coefficient , Jaccard coefficient and Simple Matching coefficient (SM) , cluster analysis was done. The relationship among the species was discussed. The result indicated that Prunus mume‘Meiren’was the most close to Prunus
mume and Prunus cerasifera‘Pissardii’, and distantly related to plum , peach and apricot , conforming to morphological classification and breeding record.

Key words: Prunus mume Sieb. et Zucc., Prunus mume ‘Meiren’, Genetic relationships, Amplified Fragment Length Polymorphism
