摘要

Oil palm is a critical global crop for vegetable oil production, yet its productivity is hindered by suboptimal fruit set. Fruit set values in oil palm plantations often fall below the optimal threshold, necessitating innovative solutions. This systematic review employed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identified 46 eligible related studies from Scopus, PubMed, and Google Scholar. This article also meets the requirements set out in the PRISMA checklist. A comprehensive search across Scopus, PubMed, and Google Scholar reveals a limited explicit focus on biotechnological approaches for fruit set improvement. This systematic review reveals breeding tools through biotechnology to improve fruit set, addressing a critical research gap, as existing studies predominantly focus on yield or oil quality rather than fruit set-specific interventions. Key findings highlight the role of multi-omics approaches, including genomics, transcriptomics, proteomics, and metabolomics, in elucidating biological processes influencing floral development, pollination efficiency, and fruit maturation. This article also addressed tissue culture as tools for propagation of elite genotypes, genetic transformation (e.g., CRISPR), and marker-assisted selection (MAS) to enable precise trait manipulation, accelerating breeding cycles. This review summarizes the highlights and implications for future breeding strategies to improve fruit set in oil palm and sustainably improve oil palm productivity.
