Genetic diversity and differentiation across Cerasus and P. avium accessions from different geographic regions. A Degree relationship network of 384 Cerasus accessions. The shades of line color are proportional to the calculated identity-by-descent (IBD) values. B Phylogenetic tree of 87 P. avium accessions from different geographic regions after IBD filtering. C Nucleotide diversity (π) estimation from different geographic regions. D Tajima’s D estimation from different geographic regions. E Nucleotide diversity (π) and genetic differentiation (FST) within different geographic regions calculated using the sliding window approach (100 kb windows with 100 kb steps). The circle size represents the mean value of π in each region. The numbers marked between each regions indicate the mean value of FST. F Linkage disequilibrium decay among different regions
