dc.descriptionThe purpose of this study was to evaluate yield stability, adaptability and environmental stratification by the methods AMMI (Additive Main Effects and Multiplicative Interaction Analysis) and GGE (Genotype and Genotypes by Environment Interaction) biplot and to compare the efficiency of these methods. Data from the evaluation of 20 experimental single-cross and three commercial hybrids and 11 locations, in two growing seasons, 2005/2006 and 2006/2007 were used. Analyses of variance, adaptability, stability and environmental stratification were performed. A better combination of adaptability and stability was observed in the hybrids 10 and 16, according to the graphics of AMMI and GGE biplot methods, respectively. The number of locations could be reduced by 28% based on stratification. The predictive correlation of the AMMI and GGE methods was 0.88 and 0.86, respectively. The results showed that it is possible to reduce the number of evaluation sites; AMMI tended to be more accurate than GGE analysis.
dc.descriptionO objetivo desse trabalho foi avaliar a estabilidade, adaptabilidade e estratificação ambiental, por meio dos métodos AMMI (Additive Main Effects and Multiplicative Interaction Analysis) e GGE (Genotype and Genotypes by Environment Interaction) biplot e comparar a eficiência destes métodos. Utilizaram-se dados da avaliação de vinte híbridos simples experimentais e três comerciais, em onze locais e duas safras, 2005/2006 e 2006/2007. Foram realizadas as análises de variância, adaptabilidade, estabilidade e estratificação ambiental. Os híbridos 10 e 16 apresentaram melhor combinação entre adaptabilidade e estabilidade, considerando os gráficos dos métodos AMMI e GGE biplot respectivamente. A estratificação promoveu uma redução 28% no número de locais. Os métodos AMMI e GGE apresentaram correlação preditiva de 0,88 e 0,86 respectivamente. Pelos resultados obtidos conclui-se que é possível reduzir o número de locais de avaliação; a análise AMMI tendeu ser mais acurada que a análise GGE.
