From: Genome wide association study reveals novel QTL for barley yellow dwarf virus resistance in wheat
Manhattan plots and Quantile-quantile (Q-Q) plots for genome wide association study (GWAS) of BYD resistance in 335 wheat accessions. a Manhattan plot in Q method; b Manhattan plot in K method; c Q-Q plot in K method. In Manhattan plots, significant association was identified using criterion of –log10 (P) > 3 (P < 0.001). Q-Q plots were displayed in marker–trait association analysis. The black line represents the expected line under the null distribution, while the red symbol in the observed –log10 (P) for BYD resistance
