Which genotype won in which environment
See which-won-where, but read entries as genotypes and testers as environments.
To the rank-2 approximation (i.e., to the approximation of the biplot),
- The genotypes at the vertices are the most responsive genotypes; they are either the best or the worst genotypes in one or more environments;
- The best genotype for an environment is the vertex genotype for the sector in which the environment resides.
- The vertex genotype is the best genotype for all environments falling in its sector.
