Manhattan plot of genome-wide association analysis for root and shoot-related traits at five stages. a–h Manhattan plot of genome-wide association analysis for SFW, SDW, RFW, RDW, TRL, TRV, TNR, and TSA, respectively. The different colours represent the trait-related SNPs at 13 DAS, 10 DAT, 3 EL, 5 EL, and 7 EL, respectively. The horizontal black lines indicate the significance threshold of GWAS (− log101/23,542 = 4.37). The x-axis shows the 19 chromosomes (A1–A10 and C1–C9) in B. napus. Each chromosome is scaled by the physical chromosome length
