Haplotype block analysis of an Argentinean hexaploid wheat collection and GWAS for yield components and adaptation

Table 3 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
