Fig. 2 The section of linkage group (LG) J of the Blackhawk x Davis population showing the position of molecular markers (SSR and RFLP) and the Rcs3 gene for resistance to frogeye leaf spot (FLS) in soybean. A marker name and position are shown on the left and the estimated map distances (cM) are shown on the right of the LG. A Satt or a Sct_ prefix indicates a SSR marker locus. An RFLP marker locus is identified with a probe designation (a capital letter code with a number code) followed by a dashed number code
