Ancient wheat and corn varieties survive the global warming

Scientists in Mexico have found that ancient wheat and corn varieties have particular drought-and heat-resistant traits. So, researchers at the International Maize and Wheat Improvement Center in El Batan are developing new strains which they can cross with plants grown from the ancient seeds. They hope these plants can fight off the ill effects of rising temperatures and the new plants are inheriting traits from the old seeds such as longer roots that suck up water and a capacity to store more nutrients in their stalks.
