Carr., a species that ranges broadly across northeastern to south-
western China, plays a vital role in the maintenance of the structure and function of these ecosystems. In this
study, we examined the genetic diversity of ﬁve widespread populations in Shanxi Plateau, the distribution cen-
ter of Chinese pine, using 15 random ampliﬁed polymorphic DNA (RAPD) primers and ﬁve inter simple
sequence repeat (ISSR) primers in 140 individual tree samples. Similar genetic differentiation results were
obtained from the data of RAPD and ISSR. Based on the two sets of data, Nei’s genetic diversity was 0.2842
and 0.3078 and Shannon’s indices of diversity were 0.4332 and 0.4468. Genetic diversity at the species level
was found high relative to that for other genera of
. The greatest diversity was observed in the
Lingkong Mountain population (0.3860), while the lowest was recorded in the Luya Mountain population
(0.3352), most likely as a result of natural adaptation and anthropogenic perturbation. The relative magnitude
of differentiation among populations (
) was 0.1491 and 0.1356, respectively, implying that most genetic
variation was within the populations (~0.8509), rather than among populations.
