Scientists Discover Wheat Landraces with Resistance to Impacts of Climate Change
October 12, 2022| |
Scientists from the International Maize and Wheat Improvement Center (CIMMYT) and the Universidad Autónoma Agraria Antonio Narro analyzed bread wheat landraces to discover traits for resistance to the impacts of climate change.
The team looked at seven climactic variables, including mean temperature, maximum temperature, precipitation, precipitation seasonality, heat index of mean temperature, heat index of maximum temperature, and drought index using genome-environment associations (GEA) and environmental genome-wide association scans (EnvGWAS), which have traditionally been poorly applied in this type of research.
From a sample of 990 bread wheat landraces from the CIMMYT genebank, the scientists discovered proteins associated with tolerance to drought and heat. With this discovery, new genotypes with resistant alleles can be selected for breeding programs to produce resistant varieties adapted to extreme environments and the impacts of climate change.
