Ganoderma in oil Palm: Hypothesis of natural infection and implementation of an early artificial inoculation test to screen oil palm progenies for their level of resistance
Genetic resistance to basal stem rot (BSR) of oil palm is an important component of an integrated disease control strategy. Early detection of susceptibility or resistance level is essential for a breeding program and for the sustainability of this crop, particularly in Southeast Asia. A screening test for oil palm progenies was developed and validated using planting material from two private companies in Indonesia, PT PP London Sumatra Indonesia (Lonsum) and PT Socfin Indonesia (Socfindo) -. The first symptoms of the disease appeared between 8 and 10 weeks after inoculation of germinated seeds. The analysis of the crosses tested showed a positive correlation between 16 and 28 weeks, indicating that early detection is realistic and that there is minimal interaction of the susceptibility to the disease over time. The main objective of this paper is to highlight the efficiency and reproducibility of this early pre-nursery inoculation test to detect approximately 100 progeny per month.
