Fig. 2From: Single nucleotide polymorphism (SNP) markers for genetic diversity and population structure study in Ethiopian barley (Hordeum vulgare L.) germplasmPrincipal component analysis showing the clustering among the region of origins of 105 barley genotypes using 10,103 SNP markers. The genotypes are grouped into three main groups. Colored dots are genotypes from various region of origins and grouped by regions, according to the legend. PC1 and PC2 are shown on the X and Y-axis, respectively, aside from their explained variance. Abbreviations: SNNPR = Southern Nations, Nationalities and Peoples RegionBack to article page
