Biplot analysis is a useful tool in plant breeding and agriculture research. It helps scientists understand how different genotypes perform in different environments. The researchers reviewed the basic principles of biplot analysis and how it can be used to analyze data from multi-environment trials. They explained how to interpret the results and provided a user-friendly software called "GGEbiplot" for analysis. This tool can help breeders and agronomists make better decisions when selecting genotypes for different environments.
