One of the fundamental requirements for conservation and use of forest tree genetic resources is understanding the biological dynamics of genetic variation within and between species. Considerable variation exists among tree species with respect to the extent of genetic diversity and the way such diversity is organised within and among populations. We have evaluated the genetic diversity and resources in some highly economic forest tree species in Thailand such as pine (Pinus merkusi and P. khasya), neem (Azadirachta indica var. siamensis, A. indica and A. excelsa), rattans (Calamus spp.), paper bark tree (Melaleuca cajuputi) by using isoenzyme gene and DNA markers. The genetic diversity between Pinus spp. and Azadirachta spp. as well as within the mentioned species are demonstrated. Besides, species specific RAPDs (Randomly Amplified Polymorphic DNA) markers are developed for rattans identification. The suggestion for the conservation of forest resources in Thailand is discussed.
