Biplot analysis of genotype by
environment data
Four objectives of genotype by environment data analysis
Environment evaluation based on GGE
biplots
Relationships among test environments
Discriminating ability of test environments
Representativeness of the test environments
Ideal test environments for selecting generally adapted genotypes
Mega-environment identification
Genotype evaluation based on GGE biplots
Performance of genotypes in specific environments
Ranking the genotypes based on performance in one environment
Ranking environments based on the performance of a genotype
Mean performance and stability of the genotypes
Ranking genotypes relative to the ideal genotype
Similarity among genotypes
Comparison between any two genotypes
Which-won-where
Comparison among three genotypes
