Background: Xi Junecry (Pinellia ternata), a perennial herb of the Araceae family, is indigenous to Xinxian County, Henan Province, China, and regarded as premium variety among similar medicinal materials. However, lack comprehensive genetic information on germplasm resources has constrained cultivation identification high-quality varieties. Methods: In this study, six chloroplast genomes were assembled annotated using high-throughput sequencing. Subsequently, comparative analyses conducted, phylogenetic tree was constructed. Results: The genome lengths ranged from 157,456 158,406 bp, GC content between 36.0% 36.2%. A total 265 single nucleotide polymorphism sites identified across genomes, with whole-genome diversity (Pi) value 0.00084. Among four genomic regions, small single-copy region exhibited highest Pi, followed by large region, while inverted repeat showed lowest. Nucleotide in coding regions significantly lower than non-coding regions. Nine hypervariable identified, follows: ndhE-ndhG, trnN-GUU-ndhF, trnS-GCU-trnG-UCC, atpB-rbcL, psaI, accD-ycf4, psbE-petL, psaC-ndhE, psbI-trnG-UCC. Positive selection detected accD rbcL genes. Phylogenetic analysis clustered samples into distinct clade, separating them other regional Pinellia samples. Conclusions: These findings elucidate variation levels provide high-variability loci for population history inference, assessment, species domestication studies, new cultivar development.
