A USDA Economic Research Service report traces the development, adoption and management of drought-tolerant corn in the U.S., from conventional breeding in 2011 to genetically engineered hybrids from 2012. It notes that most drought-tolerant corn planted in 2016 carried one or more GE traits and that crop insurance and disaster payments do not fully offset drought losses.
Wider adoption of drought-tolerant hybrids can lessen weather-driven yield losses over time and support more stable corn supply. The report is a background study with no immediate price impact.
