Within-population genetic diversity of indigenous chickens of Asia: dataset compiled from published molecular studies

This dataset contains 652 population-level estimates of within-population genetic diversity for chickens (Gallus gallus domesticus) of Asia, extracted from the full text of 87 peer-reviewed studies published between 2000 and 2026. Coverage- Local populations from 18 Asian countries (indigenous breeds, locally developed breeds and transboundary breeds in their area of origin; 588 estimates), plus the reference populations reported in the same tables of the source studies: introduced breeds and commercial lines (44 estimates) and red junglefowl (20 estimates). Populations from Taiwan are listed under China, following the country list of the FAO Domestic Animal Diversity Information System (DAD-IS).- Marker classes: microsatellites (356 estimates, 39 studies), mitochondrial DNA (175 estimates, 26 studies) and genome-wide SNP or indel data (121 estimates, 23 studies).- Parameters: expected heterozygosity (He), observed heterozygosity (Ho), inbreeding coefficient (FIS), haplotype diversity (Hd), nucleotide diversity (π) and genomic inbreeding from runs of homozygosity (FROH), with sample size and number of loci where reported. MethodsStudies were identified through a Scopus search (titles, abstracts and keywords; publications from 2000 onwards; search date 28 October 2026) and screened on title and abstract. Molecular studies whose abstract indicated population-level diversity estimates were read in full. Values were taken only from the full text (tables, text or printed figure values), never from abstracts, and are given as reported in the source study. Articles in Chinese and scanned articles were read from rendered page images. Values that were internally inconsistent in the source article are flagged (Inconsistent_flag = Yes) and were excluded from all summaries. The full search string and screening flow are given in the sheet Search_procedure. Files- Asian_chicken_within_population_diversity_dataset.xlsx: sheets README, Variables (definition of every column), Data (652 estimates), References (87 source studies, S1–S87) and Search_procedure.- Asian_chicken_within_population_diversity_dataset.csv: the Data sheet in UTF-8 CSV format.Each row gives the location of the values in the source article (table, figure or section), a note on the values, the study identifier and the full reference with DOI. Empty cells indicate values not reported in the source study.
