Abstract
Oil palm productivity improvement remains a strategic scientific focus given the crop’s economic importance and its biological complexity as a perennial species. Conventional breeding approaches have achieved significant gains; however, their effectiveness is constrained by long selection cycles and limited precision in improving complex traits. Consequently, genomic engineering and tissue culture propagation have emerged as complementary approaches to accelerate yield enhancement and improve agronomic performance. This study aims to systematically analyze and integrate contemporary peerreviewed evidence on how genomic and molecular tools, together with tissue culture technologies, contribute to the development and performance of high-yield oil palm clones. This study employs a Systematic Literature Review (SLR) design guided by the PRISMA framework. Data were collected from Scopus using predefined Boolean keyword combinations. A total of 33 English-language, open-access articles published between 2021 and 2026 were selected through sequential screening for relevance, publication year, and accessibility. Findings were analyzed through thematic synthesis and qualitative comparison. The results identified six dominant analytical clusters encompassing yieldassociated genetic traits, genomic and molecular selection tools, tissue culture propagation techniques, clonal fidelity management, agronomic performance outcomes, and productivity enhancement across cultivation contexts. The reviewed literature consistently indicates that integrating genomic engineering with optimized tissue culture propagation enhances yield potential, genetic stability, and field-level performance of clonal oil palm materials. In conclusion, genomic engineering and tissue culture propagation collectively form an integrated framework for developing stable, high-performing oil palm clones. Future research is encouraged to strengthen multi-omics integration and expand long-term fieldbased evidence to further refine clone development strategies.
