Biplot analysis helps plant breeders and agricultural researchers understand their data better. Some statisticians are unsure about using biplots, but they can be valuable tools. It's important to choose the right type of biplot for the research goal and interpret it correctly. By using GGE biplots, researchers can evaluate genotypes and test environments effectively. The adequacy of a biplot can be judged visually, and the significance of the pattern can be tested statistically.
