RESUMO
The present work has the following objectives: to propose a systematics for the study and the interpretation of the phenotypic stability and adaptability, through several multiway models (PARAFAC and Tucker3); to propose a graphic, called of Triplot, that it makes possible to evaluate the relations between the 3 ways (genotypes, locations and years); to implement a computational routine for the data analysis, according multiway models; to implement a computational routine for the construction of Triplot. The used data are relative the experiments with 13 genotypes of beans that had been lead in 9 experimental distinct ones constituted by agricultural years of 2000/2001, 2001/2002 and 2005/2006, by Dourados and Aquidauana cities, where the experiments had been installed at the time of waters (Dourados) and also at the time of dries (Dourados and Aquidauana). Each location is constituted of city and time of installation. The results indicated that the graphic triplot and joint plot, facilitate the agreement of triple interaction and bring to the researcher more real information about triple interaction, of what AMMI model of two way; the graphic triplot, helps to identify stabels genotypes, locations and years, inside of a great group of genotypes, location and years; in a general recommend to use triplot and joint plot together, to get better interpretations of the results; the genotype 6 is what less contributes for the triple interaction and genotypes 12, 9 and 5 are the that more contribute for the interaction.
