CIMMYT scientists are using the biodiversity of forgotten wheat varieties from across the world to find those with heat- and drought-tolerant traits.
Researchers use genome-wide association mapping approach to identify new regions with resistance to the disease.
Over millennia, natural selection and humans have systematically adapted the plant species that provide food and other vital products, changing their physical and genetic makeup for enhanced productivity, nutrition and resilience. Plant breeders apply science to continue improving crop varieties, making them more productive and better adapted to climate extremes, insects, drought and diseases.
Review proposes ways to accelerate climate resilience of staple crops, by integrating proven breeding methods with cutting-edge technologies.
Researchers found that prediction performance was highest using a multi-trait model.
