Detection of heterotic QTLs by GWAS across thirty F1 populations. a Comparison of the GWAS signals, illustrated as Manhattan plots, for DTT in the maternal population, and for DTT and mid-parent heterosis of DTT (MPH.DTT) in the MG1544 F1 population. The three dashed lines colored in red, green, and blue represent three significance thresholds with p-value = 2.2e− 07, 1e− 06, and 1e− 05, respectively. b Summary of QTLs for DTT (red) and MPH.DTT (green) detected in each F1 population and merged QTLs from the thirty F1 populations, compared to the QTLs in the maternal population (blue). The three dashed lines colored in red, green, and blue represent three significance thresholds with p-value = 2.2e− 07, 1e− 06, and 1e− 05, respectively. c Comparison of the GWAS signals, illustrated as Manhattan plots, for plant height (PH) and MPH.PH detected in the MG1544 F1 population. The three dashed lines colored in red, green, and blue represent three significance thresholds with p-value = 2.2e− 07, 1e− 06, and 1e− 05, respectively. d Summary of QTLs for PH (red) and MPH.PH (green) detected in each F1 population and merged QTLs across the thirty F1 populations, compared to the QTLs in the maternal population (blue). e Comparison of the GWAS signals, illustrated as Manhattan plots, for ear weight (EW) and MPH.EW detected in the MG1544 F1 population. The three dashed lines colored in red, green, and blue represent three significance thresholds with p-value = 2.2e− 07, 1e− 06, and 1e− 05, respectively. f Summary of QTLs for EW (red) and MPH.EW (green) across the thirty F1 populations, compared to the QTLs in the maternal population (blue)
