Sixteen different types of common beans were tested in Kagera region to see how well they grew in different environments. The study found that some genotypes, like SSIN 1240 and SAB 659, were more stable and had higher grain yields compared to others. These genotypes could be good choices for improving bean varieties in the future. The research used statistical models to analyze the data and showed that the environment had a big impact on the beans' growth, as well as the specific genotype used. Overall, certain genotypes performed better across different environments, making them promising candidates for further development.
