Log-likelihood-ratio (LR) profiles of testing the genomic distribution of QTLs throughout eight linkage groups for main stem traits, stem height (A), stem diameter (B), and stem taper (C) in the first growing season of mei F 1 hybrids grown in the field. The positions of markers are indicated as ticks on the x-axis. Multiallelic intercross markers (with four genotypes), biallelic intercross markers (with three genotypes) and testcross markers (with two genotypes) are shown in red, blue, and green, respectively. The horizontal lines are the genome-wide critical thresholds at the 5% significance level determined through the FDR adjustment.
