This study investigated the genetic diversity and genomic variation in wild Cordyceps chanhua populations from four regions China—Dazhou, Sichuan (ICD); Lu’an, Anhui (ICL); Taizhou, Zhejiang (ICT); Yixing, Jiangsu (ICY)—to elucidate differentiation patterns provide a scientific foundation for resource conservation sustainable utilization. Whole-genome resequencing was performed, yielding high-quality sequencing data (Q20 > 98%, Q30 94%, coverage: 93.62–95.79%) enabling detection of 82,428 single-nucleotide polymorphisms (SNPs) 12,517 insertion–deletion markers (InDels). Genomic variations were unevenly distributed across chromosomes, with chromosome chrU05 exhibiting highest SNP density (5187.86), suggesting potential hotspot diversity. Phylogenetic analysis confirmed that all samples belonged to C. lineage but revealed significant among regions. Population structure analysis, supported by PCA, identified two distinct subgroups (G1 G2) closely associated geographic origins, reflecting influence both environmental factors on differentiation. These findings underscore substantial interregional populations, highlighting importance tailored strategies region-specific germplasm The provides critical insights support marker-assisted breeding, regional cultivation optimization, development resources.
