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

Introduction 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. Materials and methods Forty-one genetic origins of teak, including 26 open-pollinated families from a clonal seed orchard in Ivory Coast, were planted in 1997 in a replicated trial at Taliwas, Sabah, East Malaysia. Results and discussion The mortality rate and early measurements of... Mehr ...
