Abstract

SILVA, Raphael Rossi  and  BENIN, Giovani. Biplot analysis: concepts, interpretations and uses. Cienc. Rural [online]. 2012, vol.42, n.8, pp. 1404-1412. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84782012000800012.

The genotype environment interaction (GE) influences on the selection and recommendation of cultivars. Biplot analysis has been increasingly used in data analysis of complex traits in agriculture. However, the peculiarities of biplot graphic could induce the researcher to errors on interpretation. Thus, this review argues the applicability and graphic interpretation of models AMMI (Additive Main Effects and Multiplicative Interaction) and GGE biplot (genotype main effects + genotype environment interaction). Moreover, also aims to explain that it is not adequate to compare both statistical methods. It is discussed the best methodology considering the information required and the research objectives.

Keywords : AMMI; GGE Biplot; genotype environment interaction; adaptability andstability.
