Scientists are working on advancing their knowledge of and ability to produce new strains of wheat, and the USDA is there to help. Rather than genetically modifying the wheat by using bacteria or viruses with beneficial genes into the wheat and seeing if the genetic material sticks in the new wheat, they are analyzing any given strains of wheat's genome for beneficial genes. Then they'll manually select the wheat with the best combination of genes and see how they do. It's much like the old method of hybridization, but with a clearer view of what's going on. I recall that some Australian cattle herders were doing much the same thing a couple of years ago.
