Daftar Isi:
- Araucaria cunninghamii as long fiber pulp raw material needs to be considered in the future which is currently imported from other countries to supply long-fiber pulp raw material in Indonesia. The improved seed sources need to be prepared early to determine the genetic gain. Combination provenance-progeny test of A.cunninghamii in Bondowoso, East Java is one of the researches that it was built to produce improved seed of A.cunninghamii in the future. The trial is laid out in Randomized Complete Block Design (RCBD) with 28 families, 4 trees per plot and 8 replicate with a spacing of 4 x 3 m. The results show that the average of height and diameter growth at the age of 5 and 10 years were 5.47 m; 8.20 cm and 16.05 m; 20.59 cm, volume/ha of the trees were 8.02 m3/ha and 74.52 m3/ha, and mean annual increment for volume were 1.60 m3/ha/year and 7.45 m3/ha/year. At 5 years old, stem diameter was significant between provenances, while at the age of 10 years significant differences for both traits. At the age of 5 and 10 years of family and individual heritability values were moderate, h2f = 0.40 - 0.50, h2i = 0.2 - 0.3; and h2f = 0.40 - 0.47, h2i = 0.28 - 0.29, while within family heritability (h2wf) was 0.41 - 0.48). Genetic correlation at age of 5 and 10 years was quite high (rg=0.62; 0.82). Estimation of genetic gain for height and diameter by within family selection was 0.10% and 0.07% for 5 years and 0.53% and 1.01% for 10 years.
