Abstract.
An amplified fragment length polymorphisms (AFLP) technique was applied to estimate the genetic diversity in four populations of white jabon (Anthocephalus cadamba Miq.) from different islands of Indonesia. The highest genetic diversity was detected in the Kapuas population (He = 0.3339, I = 0.4894), followed by Pomalaa (He = 0.2270, I = 0.3394) and Nusa Kambangan populations (He = 0.1940, I = 0.2904), while the lowest genetic diversity was measured in the Kampar population (He = 0.1489, I = 0.2278). Analysis of population structure revealed that genetic diversity within populations (Hs = 0.2260) represented 73% of the total genetic diversity (Ht = 0.3098). The proportion of the total genetic diversity that was attributed to the population differentiation was high (Gst =0.2707). The geographic distances are not significantly correlated with the genetic distance between the populations of white jabon studied. Cluster analysis placed most accessions from the Kapuas population in a separate cluster from the accessions from the other populations. We conclude that the genetic variability of the studied white jabon accessions is structured according to the origin and the population should be further sampled to increase accuracy of measurements of the genetic diversity.
