Genetic variation across the natural distribution of the south east Asian pine, Pinus kesiya ROYLE ex GORDON (Pinaceae)

Journal article

Allozyme variation has been assessed in 9 populations (172 families) of the economically important south east Asian pine, Pinus kesiya ROYLE ex GORDON, from across its entire geographical range, using 12 isozyme loci identified by 7 enzyme systems. The mean percentage of polymorphic loci per population, the mean number of alleles per locus and the mean genetic diversity within populations were 45.4%, 1.6 and 0.153 respectively. Genetic diversity was greatest in populations from the south-eastern populations and lowest in north-western populations. In the present study G(ST) (0.121) was high compared to other studies (G(ST)=0.023 and 0.039), that sampled a restricted part of the geographic range. Two theories have been proposed to explain the present distribution of P. kesiya: (i) migration from the south through Malaysia and the Philippines; (ii) migration from the north. Data based on the analysis of isozymes would support migration from the south.
