Buying corn hybrids is more confusing than ever. In the past corn was sold as dent corn and farmers had to worry about performance issues whether it was a single-cross, three-way cross, or double-cross. Then specific markets emerged and waxy, high-oil, brown midrib, leafy and nutrient dense hybrids were marketed. Today we still have many of these hybrids with genes targeted for specific uses. Most of the confusion today about hybrid selection is due to the combinations of available transgenes that protect yield better than ever before.
