The chloroplast genome, as an important evolutionary marker, can provide a new breakthrough direction for the population evolution of plant species. Actinidia deliciosa represents one most economically significant and widely cultivated fruit species in genus Actinidia. In this study, we sequenced analyzed complete genomes seven cultivars to detect structural variation characteristics. total genome size ranged from 156,404 bp (A. cv. Hayward) 156,495 Yate). A 321 simple sequence repeats (SSRs) 1335 repetitive sequences were identified. Large-scale repeat may facilitate indels substitutions, molecular variations A. varieties' genomes. Additionally, four polymorphic DNA loci (atpF-atpH, atpH-atpI, atpB, accD) detected, which could potentially useful genetic markers further genetics studies within varieties. Site-specific selection analysis revealed that six genes (atpA, rps3, rps7, rpl22, rbcL, ycf2) underwent protein evolution. These have played key roles adaptation various environments. suggested clustered into individual branch with moderate-to-high support values. results provided foundational genomic resource will be major contribution future genetics, adaptive evolution, improvement
