Genetic Parameters on Combination of Provenance and Progeny Test ofAraucaria cunninghamii in Bondowoso-East Java

ABSTRACT

A progeny test of Araucaria cunninghamii seedling seed orchard was established on January 2008 in Bondowoso, East Java. Eighty open-pollinated families collected from six seed sources (Fak-fak, Sorong, Serui, Wamena, Manokwari and Queensland) were tested. The trial was designed with a Randomized Complete Block Design (RCBD) which comprised of 80 seedlots,
4 tree- line plots with 4 replicates. The trial was planted using spacing of 4 m x 2 m. At 36
months there were significant differences among seed sources for tree height and stem diameter. The survival rate of all seed sources was high (96.7 - 100%). Differences between families within seed source were significant both for height and diameter growth. Heritability estimates for height

were moderate (h2

= 0,43 , h2

= 0,23) and also for diameter (h2

= 0,71, h2

= 0,48). Genetic

correlation between height and diameter was strong (rg = 0.90).
