Abstract

ABSTRACT Teak clonal trial was established at Watusipat, Gunung Kidul to obtain best clonal for fast growth in order to increase productivity of privatelly owned forest of teak (Tectona grandis).  Tirdty one (31) clonal teak from Thailand and teak forest in Java Island and Muna, Sulawesi Tenggara were tested in this trial. Randomized Complete Block Design, consisting of 5 replications, and 5 tree (clone) per plot were designed in this plot. Data of the teak clonal trial were collected for growth (height and diameter at breast height) in 2 and 4 years old.  In view of the variation between clones and genetic variation of growth, the analysis of variance (ANOVA) and genetic parameters were conducted.  The results showed that significant differences were found   between clones in the trial for height and diameter in 2 or 4 years old. The average of height were 5.10 m in 2 years old and 8.88 m in 4 years old, the average of diameter were 5.86 cm in 2 years old and 9.21 cm in 4 years old.  Clonal repeatabilties were low in the trial (H2C=0.07 for height and H2C=0.08 for  diameter in 2 years old; H2C=0.13 for height and H2C=0.12 for diameter in  4 years old). Base on these results, it can be conclued that the breeding program of teak can improve the mean annual increment (MAI) while using clonal selection. Therefore, the main goal for increasing productivity of teak privatelly owned forest, will be achieved. Keywords: Genetic, Clone, Teak,Variation, Growth
