Fig. 4From: Single nucleotide polymorphism (SNP) markers for genetic diversity and population structure study in Ethiopian barley (Hordeum vulgare L.) germplasmHeat map analysis shows relationship distance based on the color distribution among 105 barley populations genotyped using 10,103 SNP markers (for genotypes name and collection origins refer to Additional file 1: Table S1). Colored plots on the left side are entry genotypes, regions and clusters at the various stages, according to the legend to the right. On the left of the matrix, barley genotypes are grouped into four distinct clusters.
