Income of oil palm planters comes from the quantity of fresh fruit bunch (FFB) combining with the bunch weight harvested. This study focused on the direct and indirect effects of fresh fruit bunch and bunch weight using path analysis. Ninety tenera oil palm bunches were counted, weighed and individually separated. The results showed that bunch number (BNO) was a factor effect directly more than the average bunch weight (ABW), while a negative correlation was found between BNO and ABW, confirming that if the number of bunches was high, the ABW was small. Bunch weight (BW) composed of 9 characters interesting in this study: rachis weight per bunch (RCIS/B), rachillae weight per bunch (RCHAE/B), fruit weight per bunch (FW/B), fruit to bunch (FTB), mesocarp to fruit (MTF), kernel to fruit (KTF), shell to fruit (STF) and mean nut weight (MNW) were highly significant. Bunch weight (BW) was used to determine which components were effective. Fruit weight per bunch (FW/B) had the highest direct effect, followed by rachillae weight per bunch (RCHAE/B). Therefore, BNO and FW/B were selected to focus on fresh fruit bunches in the oil palm breeding programs.
