For calculation see von Korff et al. [34]. 9)Trait value of homozygous exotic genotypes Hsp in terms of Lsmeans across years.10)Relative performance of the homozygous exotic allele, RPHsp, a “-“indicates a reduction in trait value. 11)The additive effect is half the difference between the phenotypic means of the homozygous elite and exotic marker genotypes.
