| Summary: | The use of superior seeds or clones in an effort to increase the productivity
and allows the rotation cycle is relatively short in plantation forest management,
however, another element that is very important and needs to be considered is the
quality of the wood produced, quality is very influential on the selling value of
products the wood.
This study aimed to evaluate the planting of clonal test of Teak
cooperation Perum Perhutani with the faculty of forestry UGM planting in 1999,
in order to obtain information on the genetic correlation in growth rate and wood
quality based on the specific gravity of wood produced. Data collection was
conducted census study consisted of measurements of tree height and stem
diameter and specific gravity measurements with pilodyn penetration approach in
a position that is uniform and easily implemented at an altitude of 1.3 m or
diameter breast height as much as 2 times the penetration on every trees the entire
population (census).
The results show there is genetic variation among clones tested in Cepu
and ciamis site and combination of both sites on tree height , dbh and specific
grafity of wood. Interaction between clones with locations showed significant
differences of the height and specific grafity of wood, whereas the diameter of the
characters did not show significant differences. Valuation of broad sense
heritability for the character of height, diameter and specific grafity of wood
respectively of 0,18, 0,52 and 0,71 for the location of Cepu
