Multiattribute Response of Maize Genotypes Tested in Different Coastal Regions of Brazil

Abstract EN

This work applies the three mode principal components analysis to analyze simultaneously the multiple attributes; to fit of models with additive main effects and multiplicative interaction effects (AMMI models) and the regressions models on sites (SREG models); to evaluate, respectively, the multivariate response of the genotype × environment interaction and the mean response of 36 genotypes of corn tested in 4 locations in Brazil.

The results were presented by joint plots to identify the best genotypes for their adaptability and performance in the set of attributes.
