Genetic relationship analysis and cultivar identification of Spathiphyllum using SRAP marker

The sequence related amplified polymorphism（SRAP）marker was used to analyze genetic diversity of 23 samples of Spathiphyllum. Thirty primer pairs generated 343 bands，214 bands（62%）of which were polymorphic ones. Revealed by NTSYS software，the SM coefficient of genetic similarity ranged from 0.36 to 0.98，which indicated that genetic basis was relatively abundance among the 23 Spathiphyllum resources. A dendrogram was constructed based on SRAP data using UPGMA cluster method. The 23 samples of Spathiphyllum were classified into 3 major groups. The genetic diversity and relationships of Spathiphyllum resources were studied at molecular level for providing new molecular evidences of utilization and exploitation of germplasm resources of Spathiphyllum.
