The increasing demand for wood owing to societal development has highlighted the potential of Albizia odoratissima, a valuable timber species, address significant shortages in China. However, lack effective genetic and genomic resources limited utilization this species. In study, we utilised 95.3 Gb HiFi reads assemble draft genome A. resulting size 788 Mb, comprising 511 contigs. We conducted whole-genome resequencing on 106 individuals from 7 populations Hainan Island explore these resources. Our analysis identified 498,308 high-quality single nucleotide polymorphisms, which were used assess diversity, structure, demographic history odoratissima Island. results indicated that diversity is relatively low (observed heterozygosity = 0.189, expected 1.319 × 10−4) with minimal differentiation (Fst 0.0151) among seven populations. Furthermore, molecular variance, principal coordinate analysis, neighbour-joining tree structure revealed shallow population structure. linkage disequilibrium (LD) decay ranged 11.4 kb Jianfengling (JFL) 39.2 Wuzhishan (WZS). LD decay, history, Tajima's D analyses WZS experienced bottleneck effect. This study offers new insights into Island, providing foundation future resource improvement strategies
