          Abstract

          O objetivo deste trabalho foi verificar a presença de interação genótipo x ambiente (G x A) e determinar a adaptabilidade e estabilidade fenotípica de linhagens de algodão de fibra marrom, utilizando o modelo de Ebehart & Russell. Foram conduzidos sete experimentos nos estados de CE, GO, MS e RN, em 2010 e 2011, em regime irrigado e de sequeiro. O delineamento utilizado foi blocos casualizados com quatro repetições. Foram avaliados 11 genótipos, segundo sete caracteres relativos à fibra. A interação G x A foi significativa para a maioria dos caracteres. As linhagens 1, 2, 3, 4, 5 e 7 demonstraram capacidade de resposta à melhoria de ambiente, sendo 1 e 5 os genótipos que apresentaram comportamento previsível para todas as características. O índice de fibras curtas mostrou ser uma característica de alta previsibilidade

          The objective of this study was to verify the presence of genotype x environment (G x E) interaction and determine the adaptability and phenotypic stability of strains of brown cotton fiber using the model of Ebehart & Russell. Seven experiments were conducted in the states of CE, GO, MS and RN, in 2010 and 2011 under irrigated and rain fed conditions. The experimental design was randomized blocks with four replications. Eleven genotypes were assessed according to seven characters on the fiber. The G x E interaction was significant for most characters. The lines 1, 2, 3, 4, 5 and 7 showed better responsiveness to the environment, being 1 and 5 genotypes showed all predictable behavior characteristics for all characteristics. The content of short fibers proved to be a characteristic of high predictability
