Fig. 5From: Construction of a high-density genetic map: genotyping by sequencing (GBS) to map purple seed coat color (Psc) in hulless barleyLinkage analysis of Psc in hulless barley among all the linkage groups. Note: the x-axis is the genetic distance of each linkage group, the y-axis is the physical position of bin markers against LOD scores and the red line is the threshold LOD value as determined by a permutation test; 1~ 7, seven linkage groupsBack to article page
