Farmers and researchers have improved crops through selective breeding for millennia. Continuing to improve varieties is key to sustaining a secure supply of food, feed and fuel. Researchers and Extension specialists at land-grant universities across the United States are identifying crop varieties that can tolerate poor growing conditions, extreme weather, diseases and pests and are making sure farmers know which varieties are best suited to their farms. Scientists are also breeding tastier, healthier and more attractive varieties. These advances are increasing farmers’ yields and competitiveness, reducing production costs and providing a stable supply of high-quality products for consumers.
