The internal transcribed spacers (ITS) of the nuclear ribosomal 18S–5.8S–26S cistron have been the most popular target region in the nuclear genome. Taraxacum have been historically recognized as weedy plant and is familiar to us as medicinal herb. It comes into fashion as a new type of vegetable in recent year. In Korea, there is just fewness species type, ITS regions of wild type were amplified via the PCR method and then analysis sequencing to distinguish diversity of Taraxacum mongolicum that have been accessed in Gebank. In this study, there are difference nucleotide positions in the constitution of ITS among various type. The length of ITS regions among the two species ranged from 642 to 643bp. They had higher genetic similarities and closer relations, the species could be distinguished by their ITS sequences because they had difference genotypes on the ITS sequences. The ITS sequence of Taraxacum is relative conservation in different types. Compared in ITS sequence with Taraxacum mongolicum, result that high homology in ITS sequencing of them, the resemblance percent is above 90%.
