YSG Biotech's Teak Genetic Resources

For more than a decade, one of the primary focuses of YSG Biotech is to source and collect teak genetics from all around the world. As a result, the Company currently has one of the largest and richest teak genetic resources in the world today. In this context, special reference is given to the two Progeny/Provenance Trial Plots which were set up in 1997 in two different locations, one on a site with a hilly slope of about 150C gradient (Luasong Forestry Center, Tawau) and another in a lowland (Taliwas Forestry Center, Lahad Datu). These trials, now a clonal conservation cum seed stand, encompass 42 and 41 seedlots respectively, 26 being common to both areas. The objectives of these plots are to assess the performance and adaptation of teak genetics from diverse origins and/or sources under Sabah's conditions. For more information about these plots, kindly refer to the paper by Goh and Monteuuis (2009) on "Status of the 'YSG Biotech' program of building teak genetic resources in Sabah".
