Castanopsis tibetana is a typical and dominant component in subtropical evergreen broadleaved forests of China. However, its genetic diversity and longterm persistence have been jeopardized by habitat fragmentation. To examine its genetic diversity and genetic structure, crossspecies amplification of 51 microsatellite loci which are derived from four congeneric species, ie., Castanopsis chinensis, Csclerophylla, Ccuspidata and Csieboldii, were tested in Ctibetana.Thirtyfive loci were successfully amplified in Ctibetana, among them 11 were polymorphic across four wild populations of Ctibetana (24 individuals in total). Genetic diversity of four Ctibetana populations (Jiangxi)  was relatively low. The number of alleles (NA) ranged from 2 to 7 (average 45) and the ranges of observed (HO) and expected (HE) heterozygosities were 0505 and 0471,respectively. The results will facilitate the study and conservation of genetic diversity of Ctibetana.
