The dataset contains results from 2019 phenotypic evaluations of multi-location field trials. Also included is field level weather and soil data for the multiple locations where field testing was conducted. Data was collected by collaborators in the Genomes to Fields (G2F) initiative. G2F is an umbrella initiative to support 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. Ultimately this information will be used to enable accurate prediction of the phenotypes of corn plants in diverse environments.
