| Cohort | Oil palm seedlings (from mother palms susceptible and resistant to Ganoderma disease) were provided by the MPOB Kluang Research Station, Johor, Malaysia. The selection of parental palms for this study was based on the previous work by Idris et al. (2004). A total of 300 four-month-old oil palm seedlings from both resistant (Zaire × Cameroon) and susceptible (Dumpy Elmina × Nig) progenies, 150 seedlings from each progeny, were used in this study. Each treatment was assessed with 5 replicates per treatment through a time-course sampling. |

| Disease Introduction Mechanism | The basal stem rot disease or Ganoderma disease of oil palm is the most devastating disease occurring in tropical regions including Malaysia, Indonesia, Thailand, India, Papua New Guinea, and Africa. According to Turner and Gillbanks (2003), a productivity decline has been a concern since the replanting of oil palm began. Losses of revenue in the palm oil industry were reported to be RM 1.1 billion (USD 314 million) and RM 3.0 billion (USD 933 million) in Malaysia and Indonesia, respectively, in 2010. The white rot fungus, Ganoderma boninense, infects oil palm crops and is classified as a necrotroph. Necrotrophic fungi are inconspicuous at early stages of infection and form uniform infection hyphae within the host. These fungi degrade host cell walls to obtain nutrients by producing cell wall-degrading enzymes, and their mycelia trigger defense responses in host plants. In the final stages of pathogenesis caused by most necrotrophs, host cell death is observed before fungal fruiting bodies are formed. |
