genome assembly of Actinidia hubeiensis
The genus Actinidia, which encompasses the widely cultivated kiwifruit, is characterized by its rich species diversity. Wild Actinidia species serve as invaluable germplasm reservoirs for crop improvement. As an important kiwifruit species, Actinidia hubeiensis represents a unique taxonomic group endemic to Hubei Province, contributing valuable genetic diversity to the genus Actinidia. Here, we present a high-quality, haplotype-resolved genome assembly for A. hubeiensis. The two haplotype genomes (Hap1 and Hap2) were assembled to 658.03 Mb (N50 = 23.16 Mb) and 597.19 Mb (N50 = 20.89 Mb), respectively, and annotated with 35,741 and 36,647 high-confidence protein-coding genes. Based on comprehensive assessments, both haplotypes demonstrated high completeness (BUSCO completeness > 99%), excellent continuity (LAI up to 21.67), low base-error rates (QV > 40), and nearly complete read mapping rates (> 98%). The genome provides crucial genomic resources for the genus, enriching our understanding of kiwifruit biodiversity and offering new insights into the genetic background and evolutionary characteristics of this distinctive species.
