Table 2. Posterior mean estimates (± posterior standard deviation estimates) of genomic variance (), residual variance (), and heritability () for each maize family (families are specified by their specific parental line) and from the three different models [across-group GBLUP (A-GBLUP), within-group GBLUP (W-GBLUP), multigroup GBLUP (MG-GBLUP)].

Results are given for the traits dry matter yield (DMY) and dry matter content (DMC).
For A-GBLUP, estimates are common for all families.
