Table 3. Posterior mean estimates (± posterior standard deviation estimates) of genomic variance (${\sigma }_{\mathrm{g}}^2$), residual variance (${\sigma }_{\epsilon }^2$), and heritability ($h^2$) for each wheat cluster (Clust) and from the three different models [across-group GBLUP (A-GBLUP), within-group GBLUP (W-GBLUP), multigroup GBLUP (MG-GBLUP)]. Additionally estimates of genomic correlations (Genomic corr.) between both clusters are given.

^aResults are given for the four environments (Env) (E1, E2, E3, and E4).

^bFor A-GBLUP, estimates are common for both clusters.
