Bin linkage chromosomal map showing the locations of size (area, perimeter, length, width, length-to-width ratio), shape (circularity and roundness), weight, and color (RGB, HSV, Lab, yCbCr) for hulled and unhulled grain QTLs with the genetic distance shown in centimorgans (cM) for the rice RILs population. The color of chromosomes indicated the marker density in cM/locus.
