This study aims to define the phylogenetic relationship within Korean section sabina and find molecular markers which resolve the phylogenetic relationship in genus Juniperus and section sabina. cpDNA matK and psbA-trnH were used as molecular markers. The combined analyses of two genes suggested that section sabina was a clade supported by 100% BP. The relationships of [J. chinensis var. sargentii+J. davurica] clade and [J. chinensis var. chinensis+J. chinensis var. procumbens+J. chinensis var. horizontalis] clade were supported by 91% BP and 100% BP, respectively. Thus, the classification of Korean section sabina would be appropriate at follows, (1) J. chinensis var. sargentii+J. davurica, and (2) J. chinensis var. chinensis+J. chinensis var. procumbens According to the results of separate analyses, matK seems to work better resolving power to clarify the phylogenetic ambiguity in Juniperus and section sabina than psbA-trnH.
