The improved single nucleotide polymorphism-based consensus map of barley. The consensus genetic map is represented as concentric circles, from 1H (most central) to 7H (most outer). Chromosomes are anchored based on their respective pericentromeric regions determined with flow-sorted chromosome arms (except for 1H, where homology to rice was used). Circles represent the number of markers at each position, with both size and color representing total number of markers (blackest black = 53; grayest gray = 1). A scale bar representing 5 cM is shown as concentric arcs beside each chromosome.
