Langsat is a specific potential of tropical fruit, especially in the Southeast Asia region. The center of distribution this species in Indonesia is Sumatra region, including the Siberut Island. There are some local germplasms (landraces) of langsat from Siberut Island namely Seccet, Siamung, Telu toru gokgok, Elakmata, and Langsat padang. Analysis of genetic diversity and genetic divergence is very important for sustainable utilizing of this tropical fruit. Based on analyzed of fourteen accessions of langsat using ITS and MatK markers indicated that landrace of langsat from Siberut Island had the higher diversity of haplotypes (ITS, Hd = 0.95; MatK, Hd = 0.80) compared to those of the Sumatran mainland (ITS, Hd = 0.85; MatK, Hd = 0.28). Based on the phylogenetic trees of fourteen accessions analyzed showed that the accessions of langsat from Siberut Island were separated from accessions of Sumatran mainland.
