  • a Nomenclature of Parkin et al. (1995)

  • b The effects indicated correspond to the substitution of RR by DD at the locus in the inbred lines and to the substitution of TR by TD in the hybrids.

  • c Only dominance had a significant effect at locus wg2a6a and 0.815 corresponds to d, half the estimated dominance value (with a standard error of 0.21).
