Castanopsis tibetana is a typical and dominant component in subtropical evergreen broadleaved forests of China. However, its genetic diversity and longterm persistence have been jeopardized by habitat fragmentation. To examine its genetic diversity and genetic structure, crossspecies amplification of 51 microsatellite loci which are derived from four congeneric species, ie., Castanopsis chinensis, Csclerophylla, Ccuspidata and Csieboldii, were tested in Ctibetana.Thirtyfive loci were successfully amplified in Ctibetana, among them 11 were polymorphic across four wild populations of Ctibetana (24 individuals in total). Genetic diversity of four Ctibetana populations (Jiangxi) was relatively low. The number of alleles (NA) ranged from 2 to 7 (average 45) and the ranges of observed (HO) and expected (HE) heterozygosities were 0505 and 0471,respectively. The results will facilitate the study and conservation of genetic diversity of Ctibetana.
