To investigate the genetic diversity of Tricholoma matsutake, we studied ITS and IGS1 sequences and PCR polymorphism of a retrotransposon in 56 fruit bodies collected from 13 counties of 9 regions in Yunnan Province. We found one and three haplotypes based on ITS and IGS1 sequences, respectively. Moreover, there was no significant difference in PCR polymorphism of the retrotransposon among different populations. Compared with Jilin Province (China) and Japanese populations, although Yunnan was highly homogenous to Japanese populations, low genetic diversity of T. matsutake in Yunnan did not support the view that this species originated from Yunnan.
