摘要：Key message: ISSR characterization ofChukrasiapopulations from the natural range revealed two distinct groups of populations consonant with morphological differentiation. Results suggest the current taxonomic classification of the genus should be reviewed.Abstract: There are different views as to whether the genus Chukrasia (Meliaceae) consists of one species, C. tabularis, or two species C. tabularis and C. velutina. Despite a clear pattern of variation in many morphological characteristics such as leaves and bark, some authors regard the latter merely an ecotype of the former in seasonal forest. In the present study, we used ISSR markers to determine the genetic diversity and population structure among 23 Chukrasia subpopulations from across the natural range in Asia. Molecular analysis clearly differentiated two distinct groups of subpopulations, corresponding to the putative species, as well as well-defined subpopulations corresponding to geographic regions within the two groups. The molecular results are in concordance with morphological differentiation and corresponded to the two recognized taxa. The present study suggests that current taxonomic classification of the genus Chukrasia should be reviewed. ? 2014, Springer-Verlag Berlin Heidelberg.
