In this paper, 12 poplar clones and 4 willow clones are analysed by the software of MEGA5.0. In the study, 12 populus clones and 4 salix clones′length of ITS region sequence is 663.0bp in average. According to these samples in ITS region sequence,the base frequencies remains different in different species, the proportion of A between 17.14%~17.81%, the proportion of T between 16.79%~18.05%, the proportion of G between 31.93%~32.73%, the proportion of C between 31.89%~33.43%,the content of G +C is from 64.36%(zhaiguan)to 65.66%(Populus simonii Carr.).Populus and Salix were constructed phylogenetic tree using Neighbor-Joining and the results may reflect the genetic relationship between all clons,and so it is feasible to identify and analyze the resources of populus and salix by ITS.
