In this study, the taxonomical position of Pinus tabulaeformis f. Shekannesis Yao et Hsu was estimated on the basis of morphological characters and RAPD data. For RAPD analysis, 20 random primers were selected and 176 bands, within 172 polymorphic bands and a polymorphism rate of 97.73%, were obtained. Twenty four morphological characters data were also recorded. The RAPD and morphological characters data were then respectively analyzed with an unweighted pair-group method using an arithmetic average (UPGMA).The results based on different data are similar and it indicates that the Pinus tabulaeformis f.Shekannesis Yao et Hsü has not yet reached a variant or relatives of Pinus tabulaeformis.
