Population characteristics of the 279 sea island cotton accessions. a. A neighbor-joining tree was constructed using SNP data. b. PCA plot of the first two components (PC1 and PC2). c. Population structure analysis with K = 3. d. Nucleotide diversity (π) and population divergence (Fst) across the three cotton groups. The pie charts show percentage of introduced accessions. The value in each circle represents nucleotide diversity for this group, and the value on each line indicates population divergence between the two groups
