Broad sense heritability (H²) and variance components for the best linear unbiased predictors (BLUPs) of five traits across the tested environments

Trait	No. env.	${\sigma }_G^2$	${\sigma }_E^2$	${\sigma }_E^2$	H2
FEh	10	74.69	232.24	139.43	0.84
TGW	10	5.24	20.19	12.63	0.81
GNS	10	17.43	28.59	34.77	0.83
HD	11	89.31	143.44	39.76	0.96
PH	11	79.94	109.18	26.52	0.97

${\sigma }_G^2$ = genotypic variance; ${\sigma }_E^2$ = environmental variance; ${\sigma }_E^2$ = residual variance (here = ${\sigma }_{\mathit{GxE}}^2$ since BLUPs have a single replication per environment); H² = broad sense heritability. All genotype and environment variances were signifcant at P<0.001
