Abstract
By using ITS - nrDNA-RELP, ITS sequencing, and RAPD molecular marker, this paper studied the genetic diversity of 11 isolates in 5 races of Melampsora larici-populina from different regions. The results indicated that the genetic differentiation of M. larici-populina was correlated to its geographical distribution, which could be grouped into northern and western geographic populations, and the latter could be grouped into high-mountain forest ecologic type (HMF) and western plain ecologic type (WPL). The genetic differentiation of the race was not always corresponded with the pathogenic one. T test manifested that the genetic diversity of the 5 races had no statistic difference in RAPD markers, and the diversity index of HMF was 0.5172, being slightly higher than that of WPL (0.5089). The ITS sequence of ribosome DNA was strictly conservative, and not suitable for the genetic diversity study of M. larici-populina intra-species populations.
