Adaptability is the yield response of cassava genotypes to environmental improvement, and stability is the predictability of this response to variations. The objective of this study was to evaluate the yield stability and adaptability of cassava varieties and clones using the AMMI (Additive Main Effects and Multiplicative Interaction) methodology and auxiliary tools as supplementary genotype and environment. The responses of 24 cassava genotypes were evaluated in three environments located in the state of Alagoas, Brazil, in randomized blocks design, with 24 treatments and three replications. The effects of genotype and genotype x environment interactions significantly influenced yield. Genotypes differed regarding the adaptability and stability of yield response, and the varieties Cria Menino and Preta do Araripe were considered ideal genotypes due to high adaptability and yield stability. Among the three tested environments, Limoeiro de Anadia was the best since it presented high yield, phenotypically stable genotypes for cassava breeding programs. |
