| description | Teak is a species with high economic value and benefit, so the efforts for
vegetative propagation of superior teak clone are required. The propagation can be
done by breeding program through a clonal test. The test is done by selecting superior
clones with better growth rate and adaptability to certain environments, including in
an extreme site. Information from the clonal test can be used as a recommendation for
the use of superior clones at a production scale. The objective of this study is to
obtain the percentage rate, genetic variation in plant growth characters, tree volumebased
clone ranking, clonal heritability estimates and genetic correlation among
characters at 10-years-old teak clonal test in Watusipat, Gunung Kidul.
Observation was done to measure the values of height, diameter of breast
height (dbh), bole height, and stem form. The trial was designed by Randomized
Complete Block Design (RCBD) with 26 clones, 4 trees per plot, 5 replicates, and
spacing 2 x 3 meters. The data collected were analyzed by Variance Component
Analysis.
Results of the study indicate that the average of percentage was 88.2% and
highly significant differences among clones. Variation in all the characters among the
clones tested was also significant. The best clones were based on volume of total
height and diameter, i.e. clones number 13,18 and 8 with volumes of 0.172 m3, 0,134
m3 and 0.108 m3, respectively. Meanwhile, volume of bole height and dbh for clones
number 13, 1, 18, 8 and 10 was 0.046-0.076 m3. The estimates of heritability for all
the characters ranged from moderate to high, i.e. for height was 0.668, diameter was
0.707, bole height was 0.425, and stem form was 0.598. Genetic correlation was
positive and high, i.e. 0.976 for total height and dbh, and 0.979 for total height and
bole height. |
