Pinus merkusii Jungh. et de Vriese plantation of Java land race and three subpopulations from Aceh provenance (Jantho, Takengon and Blangkejeren) were tapped for obtaining oleoresin yield using borehole method. Data using linear regression analysis, one way ANOVA, and variability between individuals are estimated using the parameter repeatability. The results showed that, pine oleoresin production Java land races (g holes-2tree-1day-1), age class III (36.5) increased in age class IV (62.9) and decreased in age class V (24.6). The oleoresin yields on age class VI (38.3) was almost the same as the age class III. The oleoresin yields Aceh provenance (g hole-1tree-1day-1) were 21.1
