State, Brazil. All the methodologies applied showed to be able to study the stability of cassava genotypes, but each with its peculiarities. The methodologies of Eskridge, Annicchiarico and Lin and Binns were the most appropriated on situation with smaller effect of G x E interaction. The AMMI analysis and the Toler and Burrows methodology were the most specific on detailing specific adaptations of cassava genotypes to favorable and unfavorable environments. It could be suggested to use simultaneous AMMI analysis and Toler and Burrows methodology. The clone IAC 190-89 was the most promising.  aAMMI analysis  aCorrelation  aManihot esculenta  aNonlinear regression  aSafety first indexes  aStability  tBrazilian Archives of Biology and Technology, Curitibagv. 52, n. 1, p. 163-175, 2009.
