Identification of CGR QTLs by GWAS. Manhattan plots of GWAS for (a) SA, (b) SRL, (c) RA, (d) RV, (e) SW, (f) RD, (g) MRL, and (h) SL. For the Manhattan plots, -log10p-values from a genome-wide scan were plotted against the SNP positions on each of the 12 chromosomes. The horizontal light pink line indicates the suggestive threshold (p = 2.38×10−6). The grey dotted lines indicate 6 known genes that were confirmed in this study with their corresponding QTL repeatedly scanned in different traits
