Fig 4. Quantile-quantile plots for the GWAS model and Manhattan plots for the assessed traits.

Fig 4

(GI: gluten index; SDS: sedimentation index; SW: specific weight; IAS: initial agronomic score; WGP: whole grain protein; YC; yellow colour; and YIELD: grain yield). Expected and observed P values are shown on QQ-plots. Dotted blue lines represent the null model; red lines show the kinship model. Manhattan plots illustrate the marker index for each trait and the significance of the association test (as the negative logarithm of the P value).
