Mapping of P1 and R1 in each RIL population. a QTL mapping of cob color in the HO population (B73 × BY804). The red dot denotes the relative physical position of the P1 gene. b QTL mapping of silk color in the LR population (Zheng58 × HD568). The red dot denotes the relative physical position of the R1 gene
