Key message Simulations showed that hybrid performances issued from an incomplete
factorial between segregating families of two heterotic groups enable to calibrate genomic …

This study evaluates the impact of genomic prediction models on selecting inbred lines as
parents in hybrid breeding programs. New parents in a hybrid breeding program are …

We revisited, in a genomic context, the theory of hybrid genetic evaluation models of hybrid
crosses of pure lines, as the current practice is largely based on infinitesimal model …

Developing training sets for genomic prediction in hybrid crops requires producing hybrid
seed for a large number of entries. In autogamous crop species (eg, wheat, rice, rapeseed …

This chapter aims to outline the basic concepts underlying genomic selection (GS) in hybrid
breeding. First, the concepts of dominance, heterosis, combining ability and heterotic groups …

While hybrid breeding is widely applied in outbreeding species, for many self‐pollinating
crop plants, it has only recently been established. This may have had its reason in the …

Although hybrid crop varieties are among the most popular agricultural innovations, the
rationale for hybrid crop breeding is sometimes misunderstood. Hybrid breeding is slower …

Predicting the usefulness of crosses in terms of expected genetic gain and genetic diversity
is of interest to secure performance in the progeny and to maintain long-term genetic gain in …

Prediction of single-cross performance has been a major goal of plant breeders since the
beginning of hybrid breeding. Recently, genomic prediction has shown to be a promising …

Key message Calibrating a genomic selection model on a sparse factorial design rather
than on tester designs is advantageous for some traits, and equivalent for others. Abstract In …
