Waterlogging/flooding can be caused by poor drainage or excessive irrigation. Yield losses up to 50% are common in heavy, clay soils with poor surface and internal drainage. Breeding for waterlogging is a relatively new goal, and important in 2019 as farmers battle excessive rainfall. The highest yielding cultivar may not be the best choice on a poorly drained soil. We will screen current cultivars for tolerance and build breeding tools and germplasm for release to public and private institutions
