Inter-simple sequence repeat (I-SSR) markers were analyzed from diploid genomes of 95 nutmeg trees (Torreya nucifera Siev. et Zucc.) in 5 populations. A total of 62 I-SSR amplicons were observed and 7 of them were monomorphic in 95 individuals. DNA fingerprint of each tree was verified by pooling the observed I-SSR amplicons. Most of the genetic diversity was allocated within population (90.65%) and all the populations revealed similar level of I-SSR amplicon diversity within population. Degree of population differentiation (Φ_ST=9.35%) was moderate on the basis of criteria obtained from isozyme analysis. Based on the results of the cluster analysis of UPGMA, genetic relationships among 5 populations were not coincided with the pattern of geographic distribution. Non-significant confidence interval at each node also suggests that all the nutmeg populations are genetically not much differentiated.
