Fig. 1

Circos plot indicating QTLs involved in scald resistance. Barley chromosomes are indicated as coloured bars on the inner circle. Grey connector lines represent the link between the genetic position (in cM) of SNPs in the inner circle and the physical position on the outer circle (in Mbp). QTLs and resistance genes from literature are indicated inside the circle and their position is given as outlined boxes on the cM scale. The dots represent the detection rate of each SNP in 100 cross-validation runs with horizontal reference lines at 0, 50 and 100 detections. Red dots represent an average trait-increasing effect, while blue dots represent an average trait-decreasing effect across all HEB families. Black lines on the outer track indicate the range of SNPs on the physical map that have been cumulated for estimating the family-specific effect, which is presented above. Here, the lower box indicates the family with the minimal GWAS effect, while the upper box represents the family with the maximal GWAS effect. The colour code indicates the strength of the effects as a heat map, i.e. darker colour represents a stronger effect. Figure created by use of Circos [58]
