DH double haploid G2F Genomes to Fields GP genomic prediction G × E genotype-by-environment interaction TS training set 1 INTRODUCTION Genomic selection (GS) is a useful method to accelerate plant breeding progress. Researchers must allocate field trial resources among the number of replicates within an environment, the number of environments sampled, and population size when conducting multi-environment trials (MET) that support the development of genomic prediction (GP) models.

Abstract Genotype-by-environment (G×E) interactions can significantly affect crop performance and stability. Investigating G×E requires extensive data sets with diverse cultivars tested over multiple locations and years. The Genomes-to-Fields (G2F) Initiative has tested maize hybrids in more than 130 year-locations in North America since 2014. Here, we curate and expand this data set by generating environmental covariates (using a crop model) for each of the trials.
