Twelve different types of linseed plants were tested in 13 different environments in Ethiopia to see how they performed. The researchers wanted to understand how the plants interacted with the environments and which ones were the most stable in terms of yield. They found that the environments had the biggest impact on the plants' performance, followed by how the plants responded to the different environments. One particular plant, CI-1525, did well in six out of the thirteen environments. By using special analysis methods, the researchers were able to compare the plants visually and identify which ones were the best performers in different conditions.
