The comparisons of genome-wide distributions of QTLs, additive and epistasis effects for seedling traits under three seeding densities in Ex1. a seedling height; b first leaf sheath length; c first leaf length; d second leaf length; e root dry weight; f shoot dry weight. The outermost circle represented the distribution of bin markers on 12 chromosomes. The histogram plots from the second to forth circle were the distributions of additive effects under LD, MD and HD, respectively. The blue, red and green bars represented the bins with significant additive effects under LD, MD and HD, respectively, and the black bars indicated non-significant additive effects. The blue squares, red circle and green triangle indicated the locations of QTLs detected under LD, MD and HD, respectively. The blue, red and green lines in the cycle indicated significant interactions under LD, MD and HD, respectively
