Genetic diversity and kinship of ebony population (Diospyros celebica Bakh.) in its natural population in Central Sulawesi
Abstract
Diospyros Celebica Bakh. is a type of Sulawesi endemic that has a high economic value, but its existance becomes decreased due to excessive exploitation and no proper replanting. Conservation and plant development is urgently done to avoid extinction of Diospyros Celebica Bakh. Genetic diversity becomes a source of important information in conservation program and breeding for such development. This study aims to analyze genetic diversity of population and interpopulation as well as kinship among ebony population in Central Sulawesi. Leaf sample of ebony is taken from natural population in Donggala, Parigi-Moutong and Poso Regencies. Each population consisted of thirty samples (sample tree), and genetic analysis used RAPD genetic marker employing 10 primary RAPDs already selected. The results of this research showed that the average of genetic diversity of Ebony population was high (0.383), but genetic diversity among the populations was very small (0.063). The biggest genetic diversity occured in the population of Parigi Moutong, and the smallest occured in the population of Poso. The population of Ebony in Donggala and that of Ebony in Parigi Moutong are more closely related compared to that in Poso. The result also indicated that the species will be survived and exist providing the genetic diversity are well maintained, therefore in-situ and ex-situ coservation program are required.
