Data types in this directory tree are: hybrid and inbred agronomic and performance traits; soil data and weather data collected from the Genomes To Fields (G2F) project sites in the 2015 season. G2F has developed a living infrastructure of researchers across disciplines and a network of field phenotyping sites. During the 2015 growing season, G2F has conducted experiments in over 13,700 plots across 27 unique locations with 33 Principal Investigators. The overall goal is leveraging these datasets to improve phenomic predictability and facilitate the development and deployment of tools and resources that help address fundamental problems of sustainable agricultural productivity. This is a new release of the 2015 G2F data with the addition of phenotypic data for hybrids in IAH1, IAH3, and IAH4 which were not included in the previous 2015 DOI.
