Fig. 4From: Genetic characterization of inbred lines from Shaan A and B groups for identifying loci associated with maize grain yieldResults of the GWAS of grain yield in AM126. Manhattan plot (a) and quantile-quantile plot (b) in Yangling. Manhattan plot (c) and quantile-quantile plot (d) in Yulin. The red line in the Manhattan plots corresponds to the Bonferroni-adjusted threshold (P < 1 × 10− 3)Back to article page
