InfoSAWIT, JAKARTA — Indonesian palm oil research has reached a historic milestone. Supported by the Palm Oil Research Grant from the Palm Oil Plantation Fund Management Agency (BPDP), a research team from IPB University, in collaboration with PT Smart Tbk and the Indonesian Oil Palm Research Institute (PPKS), has successfully mapped the complete genome sequences of two key genetic resources of oil palm: a wild Dura from Cameroon (Eg-DCM) and the ancestral Deli Dura preserved at the Bogor Botanical Gardens (Eg-DBG).
Published in the scientific journal DNA Research, the study is likened to opening the “black box” of the oil palm genome—revealing genetic diversity that has long remained hidden within the world’s most important vegetable oil crop.
Oil palm (Elaeis guineensis) is known as the most efficient vegetable oil crop, supplying nearly 39% of global vegetable oil demand from only about 6.6% of the world’s total agricultural land. However, this success comes with a paradox. Modern oil palm varieties suffer from genetic bottlenecks because most cultivated palms today are descended from just four seedlings planted at the Bogor Botanical Gardens in the 19th century. This limitation has constrained breeding progress and increased vulnerability to pests, diseases, and climate change pressures.
Quote BPDP, InfoSAWIT reported on Sunday (January 10, 2026) that the latest research produced high-quality genome sequences with completeness levels exceeding 97%. Researchers identified approximately 39,000 genes in Eg-DBG and 35,000 genes in Eg-DCM. Most critically, more than 1,700 resistance genes (R genes) were discovered in each genome, including RLK, RLP, and CNL groups—highly valuable natural genetic resources for modern oil palm breeding.
“By opening the black box of the Deli Dura progenitor genome and wild oil palm, we can recover alleles and traits that were lost during domestication,” said Sudarsono, principal investigator of the oil palm PAN Genome project. According to him, these findings provide a strong scientific foundation for developing high-yielding palm oil varieties that are more disease-resistant and better adapted to environmental stress.
Broad Application Opportunities
The unveiling of this genomic map opens up a range of strategic opportunities. Identification of resistance genes offers new approaches to combating destructive plant pathogens. Access to previously lost alleles also holds potential for improving mesocarp development and oil content. From a climate resilience perspective, these genomic insights can guide the breeding of oil palms tolerant to drought, heat, and other environmental stresses. Furthermore, conservation of wild and ancestral oil palms is crucial for safeguarding long-term genetic resources for sustainable agriculture.
This breakthrough is regarded as a turning point in national palm oil research. By integrating genomic data into marker-assisted selection and genomic breeding, the development of next-generation cultivars can be accelerated—balancing high productivity with sustainability principles.
About the Study
The research involved scientists from IPB University, including Diny Dinarti, alongside researchers from PT Smart Tbk and PPKS Medan. The study utilized advanced sequencing technologies such as Oxford Nanopore (long reads), MGI (short reads), and Hi-C scaffolding. The results were published in DNA Research (Oxford Academic) with DOI: 10.1093/dnares/dsaf033.
With a stronger genomic foundation, the future of Indonesia’s palm oil industry now holds greater potential to grow more productively, resiliently, and sustainably. (T2)
