Fig. 4

a Linkage phase similarity (LPS) between pairwise populations for SNP pairs at different distances. SNP pairs are binned in groups of 10,000 bp intervals. b Genetic correlations of heading date between populations. c Genetic correlations of lodging between populations. d, e Power plots for different GWAS models applied to heading date (d) and lodging (e). The x-axes show the squared value of a hypothetic SNP effect. The y-axes show the statistical power of GWAS for a given marker size. Different lines types are used to display different models, whereas line colours refer to the combination of populations subjected to GWAS. The dashed horizontal lines indicate a power of 0.9.
