Forest trees cultivars developed by breeders have been increasingly deployed as clones, following long generations of breeding and testing. An established protocol for distinctiveness, uniformity and stability (DUS) testing becomes an essential element for protecting the intellectual property rights associated with these clones. DUS testing with morphological descriptors has, however, shown limitations in categorically distinguishing cultivars, especially with narrow genetic base. DNA fingerprinting based on microsatellite markers has been a powerful tool to discriminate clones. Teak (
