“…The usage of molecular marker data for implementing predictive breeding methods to support the development of new and improved varieties has strongly increased during recent years (Haikka et al., 2020; Juliana et al., 2019; Schrag, Schipprack, & Melchinger, 2019), as such a strategy can result in higher selection gains than those possible by relying merely on observed phenotypic performance of quantitatively inherited traits like yield (Rife, Graybosch, & Poland, 2018; Sleper et al., 2020). Aside from introducing genomic relationships into various prediction models, the possibility to utilize relationships based on pedigree records has been the subject of past (Bauer, Reetz, & Léon, 2006) and more recent investigations (Cappa et al., 2019). The efficiency of both pedigree and genomic selection is, amongst others, dependant on the heritability of the trait of interest as well as the availability of correlated traits that can be exploited in a pedigree‐assisted or genomic‐assisted prediction in order to increase the accuracy of estimated breeding values (Schulthess, Zhao, Longin, & Reif, 2018; Velazco, Jordan, et al., 2019).…”
