PC1 x Mean Trait
The PC1 x Mean Trait for Genotypes and Environments tab is shown below:
The PC1 x Mean Trait for Genotypes and Environments tab contains the following elements:
This biplot has the value of the first principal component from the linear-bilinear model on the y -axis and the mean trait on the x -axis, with genotypes represented by blue triangles and environments represented by red circles on the same plot.
In general, a genotype "close to" an environment, in terms of the angle between the vectors drawn from the origin to the genotype and environment symbols, shows specific adaptation to that environment. Genotype points that are close to the origin show a broader adaptation to the environments. See Gower and Hand (1996) 1 for more information about interpreting these plots.
