| Summary: | The half-sib progeny test of Shorea leprosula Miq. in PT. Sarmiento
Parakantja Timber (PT. Sarpatim) Central Kalimantan, was established to convert
into an half-sib seedling seed orchard by reason of quality seed availability was
lacking. The aims of this research were to assess variation and estimate genetic
parameters of growth, as well as to identify the rouging impact in genetic parameters
of S. leprosula. Materials of S. leprosula were collected from 72 families (60 families
from PT. Sarpatim, 4 families from PT. SJM, 7 families from PT. SBK, and 1 family
from PT. Erna Djuliawati) with 4 treeplots each family. The trials were planted using
a Randomized Complete Block Design (RCBD), with ten replications, and 6 m x 3 m
in plants spacing.
The result showed that the growth of S. leprosula progeny test was fast at 6
years old (a mean height 12,46 ± 2,47 m and a mean diameter 14,34 ± 3,131 cm).
Statistically significant differences in height and diameter were not detected among
families (Fheight=1 and Fdiameter=0,9 |
