Figure 1

The GGE (genotypic main effect plus genotype-by-environment interaction) biplot for yield for each of the five years from 2006 to 2010. The biplots were based on ___location standardized data (Scaling = 1, Centering = 2) and the singular values were partitioned entirely to the ___location vectors to focus on the relations among test locations (SVP = 2). The genotypes are shown as “+” for clarity. See Table 1 for the full ___location names.
