Characterization of putative IBD tracts in the genomes of the 113 Pyrus accessions. A The number of putative IBD tracts is based on the average pairwise individual intra-population and inter-population comparisons. The blue bars indicate intra-population comparisons, while the red bars indicate inter-population comparisons. B Boxplot of FST values for pairwise comparisons between the two different populations. C Heatmap showing the IBD tract sharing (length) among the 113 pear accessions. The 113 pear accessions comprised wild Asian (green line), wild European (blue line), cultivated Asian (brown line), and cultivated European (red line) pears. The average length of the IBD tracts within a single accession was denoted as zero in this study. The color scale at the top indicates the average lengths of IBD tracts between any two different accessions. D Principal component analysis (PCA) based on the IBD tract data. Red dots correspond to cultivated Asian pears (CA), green dots to cultivated European pears (CE), light blue dots to wild Asian pears (WA), and purple dots to wild European pears (WE). E IBD sharing among the 113 pear accessions. Dots correspond to the accessions, while lines connecting any two dots represent IBD tract sharing. The dot sizes correspond to the number of IBD tracts shared
