The results indicate that the 2DS region significantly reduces DI, DS, and VRI, while the 2DL region contributes most to the reduction of DON content. The 4B region has a relatively smaller effect on all traits but shows a significant impact on plant height (Adapted from Dhariwal et al., 2020) 6.2.2 Environmental interactions Environmental factors significantly influence the expression of many traits in wheat, adding another layer of complexity to genetic mapping. For example, QTLs for kernel-related traits were mapped in multiple environments, revealing significant environmental interactions (Ren et al., 2021). Similarly, the genetic control of
