Distinct performances caused by the interaction of genotypes versus environments make research on adaptability and stability essential for the selection of new cashew clones. So the objective was to estimate adaptability and stability using AMMI graphical analysis. The treatments were 25 clones of early dwarf cashew, implanted in a randomized block experimental design, with three replications, being evaluated: plant height (AP), crown diameter (DC) and plant phenology (FP). The most stable clones in models AMMI1 and AMMI2 are T22, T3 and T2 for AP, T23, T24, T20, T16, T8, T6 and T18 for FP and, T5 and T22 for DC, with clone T22 coinciding between AP and DC; clones T4 and T5 in AP, T11 and T21 for FP and T4 and T10 for DC contributed more intensely to the means; the years represent the greatest contributions in the phenotypic variations and generating phenotypic distinctions in the clones.
