The three QTL QA09, QC09a and QA07a (described in Table 5) were considered. The following mixed Linear model was used $Y_{\mathit{ijkl}}=\mu +G_i+E_k+marke{r}_j\times E_k+\underset{\_}{R_{l\left(k\right)}}+\underset{\_}{{\epsilon }_{\mathit{ijkl}}}$, with the genotype (G), the environment (E), the QTL (marker), the genotype by environment interaction effect (G × E) and the block effect (R) nested in the trial., as proposed by Happ et al. (2021). The QTL effect is tested using the marker presenting the highest –log(p-value) within its confidence interval. In each case, the percentage of variance explained by the considered effect is indicated
