Resumo
The aim of this study was to quantify the influence of some environmental and genotypic variables on genotype
by environment (GE) interactions in soybean. Mean yield data from eighteen test genotypes in eleven experiments in Goiás
State, Brazil, were used and analyzed by AMMI method. To identify environmental and genotypic variables related to the GE
interaction, simple linear correlations were estimated between the means of these variables and the scores of the first AMMI
principal component of the interactions. Successive simple linear regression analyses were also carried stepwise, in order to
relate the GE interaction of each genotype to the observed environmental factors. The environmental factors that influenced
the GE interactions most were altitude, maximum temperature, end-of-cycle disease complex, total rainfall and soil fertility.
The genotypic variables days to maturity and reaction to end-of-cycle disease complex were most associated with GE interactions.
