Additional file 1: of Analysis of genetic differentiation and genomic variation to reveal potential regions of importance during maize improvement

Figure S1. Correlation analysis of the first five principal components (PCs) between specific subset with different marker size and the entire set with all markers. Figure S2. Pair-comparison of DEST on different chromosomes between the subpopulations. Figure S3. Summary statistic of flowering time related traits. Histograms show the distribution of flowering time related traits. Numbers in the up-right triangle are the Pearson coefficient between flowering time related traits and between environments for the same trait. The low-left triangle is the scatter plots between flowering time related traits and between environments for the same trait. Figure S4. Comparison of the genetic variation evaluated by using two datasets including 43,252 and 85 SNPs, respectively. Each scatter presents one accession. Black line is the fitted of all scatters.
