The ITS-Is of 24 accessions belong to 10 species of subgenusGlycine, and 2 species of subgenusSoja of genusGlycine were amplified, cloned and sequenced. According to the homology of the sequences, the phylogeny of the 24 accessions were reconstructed. The reconstructed dendrogram showed that there were some divergent genomic types found in the previously classified species, such asG. tomentella, G. canescens andG. tabacina, and they might be some cryptic species by morphologic analysis.
