Abstract
There is much concern over teak (Tectona grandis L. f.) genetic resources because of uncontrolled logging during the past centuries. We investigated patterns of genetic variation within and among nine populations of T. grandis from diverse geographical regions in India, Thailand, and Indonesia using amplified fragment length polymorphism (AFLP). An analysis of molecular variance (AMOVA) showed that 57% of total genetic variance occurred within populations, the remaining 43% occurred between populations. Cluster analysis and principal coordinate analysis indicated that Indian populations are clearly separated from those in Thailand and Indonesia. However, the Berbera population from Orissa near the Indian northeastern coast is an exception, as it seems to have associations with both the Indian and the Thai-Indonesian populations. The Thai and Indian populations cannot mutually be separated in this investigation. The comparisons between Indian populations suggest that the northwestern Allapally plains population (Maharastra) is distinct from the two southern Indian populations that were analyzed.
