Abstract: In order to evaluate the genetic relationship among germplasm of Prunus mume Sieb. et Zucc.,sequence related amplified polymorphism(SRAP)marker was used to analyze genetic diversity of 135 samples of Mei. Seventeen primer pairs generated 124 bands,106 bands(87.5%)of which were polymorphic ones. SRAP primer pairs amplified 4 to 12 bands with an average of 7.3 bands per primer pair. Revealed by NTSYS software,the SM coefficient of genetic similarity ranged from 0.556 to 0.958,with an average of 0.733,which indicated that genetic basis was relatively abundance among the 135 Mei resources. A dendrogram was constructed based on SRAP data using UPGMA cluster method. The 135 samples of Mei were classified into 7 major groups,which was basically corresponded with the genetic relationships based on morphological traits.

Key words: SRAP marker, Prunus mume Sieb. et Zucc., genetic diversity
