The present research had the following objectives: to propose a systematics for the study and the interpretation of the phenotypic stability and adaptability, through Tucker3 models; assess the use of the joint plot; comparing the results obtained by tucker3 model with the results obtained by biplot analysis and AMMI models. The data used are related to the experiments with 13 genotypes of beans that had been lead in 9 distinct experiments. The results indicated that the joint plot graph facilitates the understanding of triple interaction and bring to the researcher more real information about triple interaction, than AMMI modeling of two entries. The genotype 6 was the one which least contributed for the triple interaction and genotypes 12, 9 and 5 were those e which had contributed more for the interaction.
