Accomplishments
1. Predicting how different crop cultivars will respond to varying environmental, weather, and management conditions remains a significant challenge in agriculture. Producers choose cultivars based on past performance in performance trials but do not have precise predictions of how a group of cultivars might be expected to perform on their farms. Researchers at Ames, Iowa, through participation in the Genomes to Fields Initiative, have helped to coordinate a large scale study of hundreds of corn hybrids grown in environments through the U.S. and Canada. The result of this collaboration with researchers across the U.S. is a large data set including hybrid performance data, genomic fingerprints on hybrids evaluated, and associated weather and management data. Experiments have been conducted since 2014. Two years after completion of each trial, data are released for public use. These data sets provide the largest public resource available for study of differential corn hybrid performance across many environments and will provide researchers in universities, companies and other organizations an avenue for studying new approaches to this difficult problem.
