The U.S. Department of Agriculture has approved Monsanto's genetically engineered, drought-resistant corn for sale in the U.S. after reviewing environmental and risk assessments, public comments and research data from the company, according to reports.

The variety, known as MON 87460, "is no longer considered a regulated article under our regulations governing the introduction of certain genetically engineered organisms," said the USDA. The major U.S. area for adoption of drought-tolerant corn will be the Plains, which produces one-quarter of the country's corn crop, according to Monsanto estimates.
