The number of RILs in each population is given in brackets. $V_{\text{g}}$ is the genotypic variance component, $V_{\text{env}}$ denotes the variance component explained by the year effect, $V_{\text{GE}}$ is the variance component for genotype-environment interaction and $V_{\text{e}}$ denotes the residual variance component
