Means, ranges, estimates of variance components (genotypic, ${\sigma }_{\text{g}}^2$; genotype-by-location interaction, ${\sigma }_{gl}^2$; genotype-by-year-by-location interaction, ${\sigma }_{\mathit{gyl}}^2$; and residual error ${\sigma }_{\epsilon }^2$), heritabilities $H^2$ determined from 274 winter rye hybrids assessed in two years, which were individually or combined analyzed
