Genetic variation in major phenotypic traits among diverse genetic origins of teak (Tectona grandis L.f.) planted in Taliwas, Sabah, East Malaysia

摘要

As a forest species, genetic variability is high in teak (Tectona grandis) and domestication of the species is very recent. The selection effect among qualitative and quantitative traits is therefore expected to be strong. Native provenances and clonal seed orchard families were compared in this study.
