Abstract

Glyptostrobus pensilis (Staunton ex D.Don) K. Koch is an endangered and rare plant species only distributed in Vietnam and Southern China. Assessing the genetic diversity of G. pensilis populations is important in preserving and developing this species in the future. Genetic variation within and between two G. pensilis populations (Ea H'Leo and Krong Nang) was studied using the ISSR marker. The results obtained a total of 245 bands, of which polymorphic bands accounted for 80.81%, showing that genetic variation in the G. pensilis population is at a relatively high level compared to some endangered gymnosperms other. The genetic diversity of G. pensilis is average: Na = 1.767; Ne = 1.379; I = 0.365 and h = 0.233. The genetic difference between the two populations is not large (6%) and between individuals in the same population is very large (94%) when analyzed by AMOVA. The genetic differentiation index GST = 0.0480 and the genetic exchange frequency Nm = 9.9077 indicate that the existence of genetic differences between the two studied populations is low and the differences dominate in the population.
