rDNA internal transcribed spacer analysis(rDNA ITS)was used to study diversity of 12 representative mycorrhizal Rhizoctonia strains,which were isolated from Chinese orchids(Cymbidium)distributed in different sites and belonged to different ecologic *** Blast results indicated that all these strains belonged to Epulorhiza or Tulasnella,which was fully consistent with identification as Epulorhiza with morphological ***,based on rDNA ITS sequence cluster analysis,dendrogram of Cymbidium mycorrhizal strains showed that the distributed environments and orchids species were two crucial factors that affected the specificity-relation between Chinese orchids(Cymbidium)symbiotic mycorrhizae and hosts.
