Abstract
Genomic selection studies usually use few environmental models to predict progenies from biparental crosses. However, in a maize breeding program, numerous crosses need to be evaluated in multiple field trials to identify single-crosses with greater yield potential. In this study, 614 AFLP marker effects estimated in 250 maize single-crosses evaluated in 13 environments were used to assess the influence of training population size (N), number of markers (NM), genotype-by-environment interaction (G 9 E) and population structure on the prediction accuracy (rMG) for grain yield using RR-BLUP model. Cross validation analysis were performed within and across environments, and within and across groups of related single-crosses....
