Fig. 3From: Genome-wide association mapping in a diverse spring barley collection reveals the presence of QTL hotspots and candidate genes for root and shoot architecture traits at seedling stageManhattan plots of 12 out of 21 root and shoot traits. Horizontal axis presents seven chromosomes (1H–7H) of the barley genome. Vertical axis shows -log10(P) values of the marker-trait associations. Horizontal green line shows the threshold value based on FDR (0.05). Additionally, dashed line signifies threshold of -log(p) = 4.0Back to article page
