This study aims to examine the rooting ability of 24 clones of Pinus merkusii with high resin yield. The explants were propagated by shoot cutting that produced callus. The variables of root cuttings ability were root percentage, cutting height growth, number and length of primary roots, number and length of secondary roots, root volume, root biomass, and shoot-root ratio. The study was carried out in a Completely Randomized Design with treatments of 14 clones from hedge orchard (called as pkp clone hereafter) and 10 clones from a progeny trial (called as ppt clone hereafter) with 4 treeplots and 4 replications. The results showed that clones' origin had caused differences in root percentage, length of primary roots, number and length of secondary roots, and shoot-root ratio (P value 70%). Meanwhile, the clones from the progeny trial showed better height growth.
