Proportion of variance accounted for by each component of the model for the four traits considering the four models.

The four models are a single-environment model (SM) and multi-environment models (MM, MDs, and MDe, see the definition in the method section) for each of the four traits: flowering time (FL), plant height (PH), grain yield (YLD) and zinc concentration in polished grain (ZN). The variance components are defined as for the residual variance, for the genetic variance, for the variance of the random intercept, for the variance resulting from the GxE interaction, and and are the two environment-specific variances.
