  1. a Indicate site-years included to calculate BLUP for each dataset used for genomic selection
  2. b Broad-sense heritability, calculated using the formula: H2\( =\frac{\sigma_G^2}{\sigma_G^2+{\sigma}_{\frac{GEI}{e}}^2+{\sigma}_{\frac{E}{er}}^2\ } \)
  3. c Results adapted from Mason et al. [18]
