Due to an error in the production process, legends of Fig. 1 and Fig. 2 are identical in the original publication. Given below is the correct legend for Fig. 1.

Fig. 1. Cumulative distribution of p values computed from 14,739 SNPs for naïve, Q, PCA, K, QK, and PK association mapping models with sorghum height and maturity. More uniform p value distribution indicates a better model. The lines of naïve and PCA overlap while those from K, QK and PK overlap in both traits.
