From: Detection of Novel QTLs Regulating Grain Size in Extra-Large Grain Rice (Oryza sativa L.) Lines
Frequency distributions of grain length and width and quantitative trait loci (QTLs) detected in F2 populations derived from the BG23 × LG10 cross. Frequency distributions of grain length (a) and width (b). Vertical white and black arrowheads indicate the means for BG23 and LG10, respectively. (c) Boxes indicate the positions of regions harboring QTLs with the logarithm of the odds > 3.0 for grain length (black) and width (white). Horizontal black arrowheads indicate the positions of previously cloned QTLs for grain size. Double-headed arrows indicate the positions of previously detected QTLs for grain size. Bars indicate marker position
