Genetic diversity and genetic differentiation of natural populations ofPinus kesiya var.langbinanensis

Abstract

Genetic diversity and genetic differentiation of natural populations ofPinus kesiya var.langbinanensis were examined by means of electrophoresis technique. Analysis of 9 enzyme systems including 16 loci showed that all the three natural populations of the pine were high in genetic diversity but, low in inter-population genetic differentiation. The proportion of polymorphic loci is 0.667, with each locus holding 2.13 alleles, averagely. The average expected and observed heterozygosity was 0.288 and 0.197, respectively. The gene differentiation among populations was 0.052, but the mean genetic distance was only 0.015.
