Azadirachta indica A. Juss (Apocynaceae) is a large tree of the lowland tropical rainÂ forest of Southeast Asia that occurs in Thailand, the Malay Peninsula, on the island ofÂ Java (East Java) and Lesser Sunda Islands. Its economic value was in its wood (timber),Â and as medicinal plant. The information on genetic diversity of the species is very limited.Â Hence studies were initiated and genetic diversity estimated using RAPD markers inÂ 27 accessions of A.indica procured from three geographical regions of TN Baluran andÂ Balai Litbang Kehutanan. Seven selected Operon primers (10 mer) generated a totalÂ of 133 consistent amplification products ranging from 132 bp to 5.6 Kb. The clusterÂ analysis separated the 27 individuals into 2 clusters. The range of genetic dissimilarity
value among samples was from 0.07 to 0.33, while genetic distance among populationsÂ was from 0.04 to 0.10. These values showed that A. indica from TN Baluran was notÂ genetically diverse population.Â Key words: Azadirachta indica, genetic diversity, RAPD
