Phylogenetic relationships of 147 cotton accessions. a A neighbor-joining tree was constructed using whole-genome SNP data. The cotton samples were divided into G. hirsutum races (orange), G. hirsutum cultivars (green), G. barbadense cultivars (dark blue) and outgroup species (light blue). b Population structure of cotton accessions determined using STRUCTURE. The accessions were divided into three groups when K = 3. c Principal component analysis of all cotton accessions using whole-genome SNP data. d Phylogenetic relationships between G. hirsutum cultivars and races. e Phylogenetic relationships between G. barbadense landraces and cultivars. The scale bar indicates the simple matching distance
