Summary of genetic variation and genes with signature of positive selection in different populations

Population	Number of significantly different SNPs1	Number of non-synonymous SNPsa	Number of genes having non-synonymous SNPs	Subpopulation	Genes having signature of positive selectionb
Asian	295	184	61	Wild	64
				Cultivated	60
European	122	74	39	Wild	57
				Cultivated	63

¹Significantly different SNPs means this SNP has significant (chi-square test p-value < 0.01) different alleles distribution between wild and cultivated groups. ^aNon-synonymous SNP means the significantly different SNP was also non-synonymous. ^bGenes with Ka/Ks ratio more than one were considered as having signature of positive selection in different populations
