This study was conducted to evaluate plant growth of Intsia bijuga at 5 years old in Sobang, Banten for supplying good genetic material in the future. Establishment of the trial was conducted in 2007 using Randomized Complete Block Design (RCBD) that consisted of 6 blocks, 100 families nested in 10 provenances, 4 treeplot for each family with a spacing of 4 x4 m. Measurements were taken periodically every year on the survival percentage, total height and stem diameter at the breast height or dbh. At the age of 5 years showed that the significant differences among provenance in survival percentage that ranged from 41.61 to 65.11 %, average of plant height were 1.04 to 2.82 m and dbh 1.24 to 1.59 cm. The growth variation families also showed significant differences in height and diameter. The survival rate ranged from 12.5-91.67 %, average plant height were 0.52-2.55 m and dbh 0.90-2.44 cm. Individual tree heritability estimate for height was height (0.344) while that of diameter was moderate (0.259). Family heritabilities for height and diameter was considered moderate, namely 0.573 and 0.491 respectively. Genetic correlation between height and diameter growth was positive and high (0.834).

Teak (Tectona grandis) is one of popular and important carpentry wood in Indonesia. However teak production for carpentry material cannot balance the increasing need for domestic and export market. The increased production from small holder forest can be alternative way to supply national wood need. Therefore science and technology play role to support forest productivity eg superior seedling from vegetative propagation. The preparing of superior seed took several steps i.e. selection from mother tree, genetic material extraction, grafting activity using budding technique, hedge orchard establishment, and mass production used cutting rotted or tissue culture. From clonal test we can derive superior seed which adaptive with development location and has better productivity.

Trial research of teak clones was located in Wonogiri, Central Java. This research was conducted in order to evaluate the growth performance of teak clones that can be developed for forest plantation and private forest. Establishment of teak clones test was conducted in 2002 using 20 clones with Randomized Completely Block Design/RCBD consisting of 5 ramets and 5 replications with plant spacing of 2 m x 6 m . The second plot was established in 2005 using 100 clones with RCBD that consisted of 3 ramets and 5 replications with spacing of 2 m x 6 m. The observation and measurement on height and diameter at breast height/dbh were carried out periodically in every year to determine the level of plant growth The results showed that the average growth at the age of 5 years in two test plot clones are height from 8,73 to 9,97 m , tree diameter from 8.61 to 13.14 cm and tree volume estimated 0,046 - 0,103 m3. Estimated heritability clones of tree height and diameter were 0,18; 0,29 in plot 1 and 0,32; 0,38 in plot 2.
