Table 1 Estimates of variance components and heritability (h2) for grain yield, plant height, starch content and total pentosan content among 220 test-cross progenies each, obtained using F 3:4 from two bi-parental segregating populations, population A and population B

From: The accuracy of prediction of genomic selection in elite hybrid rye populations surpasses the accuracy of marker-assisted selection and is equally augmented by multiple field evaluation locations and test years

  1. σ G 2 refers to the genotypic variance, σ G × E 2 represents the interaction variance between genotype and environment, and σ Eff . Error 2 denotes the variance of effective error.
  2. **Significantly different from zero with P < 0.01.
