Fig. 6
Trait–QTL network constructed for all of the investigated traits and the underlying consensus QTL. Traits and consensus QTL are treated as nodes, which are drawn using the hexagon and circle, respectively. The seed yield, yield components and yield-related traits are distinguished by the different colors. The additive-effect direction of these consensus QTL is distinguished by the lines of different endpoint types (+ : arrow; -: vertical line). The abbreviations of trait names are the same as those in Table 1, and the width of the lines indicates the R2 of the consensus QTL
