The researchers studied how different types of wheat grow in different areas of Ethiopia. They found that some wheat types were more stable and produced higher yields in certain locations. The study showed that environmental changes can greatly affect wheat growth, and it's important to choose the right wheat types for each area. The wheat types Digelu and ETBW6738 were the most stable and had higher yields, while Danda'a and ETBW6732 were less stable. Some locations like Bokoji and Kulumsa were good for wheat growth, while Areka was not as good. Overall, the study highlights the importance of choosing the right wheat types for different environments to ensure good yields.
