The distribution and effects of single QTL identified for 19 oil related traits in KUI3/SC55 RIL population. a Distribution of single QTL on chromosomes. QTL regions across the maize genome are represented by confidence intervals, and LOD values are scaled by color. b Total PVE of single (blue bars) and epistatic (red bars) QTLs for each trait. c Effect size (represented by PVE) and the origin of the increasing alleles of the identified QTLs. Blue and red bars indicate that increasing alleles come from KUI3 and SC55, respectively
