The dataset contains results from 2020 phenotypic evaluations of multi-location field trials of Maize GxE within the Genomes to Fields (G2F) initiative. Collaborators also collected field-level weather and soil data for the multiple field testing locations. G2F is an umbrella initiative to support the translation of maize (Zea mays) genomic information for the benefit of growers, consumers, and society. This public-private partnership is building on publicly funded corn genome sequencing projects to develop approaches to understand the functions of corn genes and specific alleles across environments. The use of large-scale datasets contributes to the accurate prediction of the phenotypes of corn plants in diverse environments.
