Mining valuable genetic variants for climate change adaptation from the world’s largest cassava collection

Climate change is challenging crop production, threatening food security and the livelihoods of billions of people. A total of 13,518 cassava landraces are conserved by nine genebanks globally. Among these, the International Center for Tropical Agriculture (CIAT) in Colombia, conserves 4,947 landrac...

Sumario:Climate change is challenging crop production, threatening food security and the livelihoods of billions of people. A total of 13,518 cassava landraces are conserved by nine genebanks globally. Among these, the International Center for Tropical Agriculture (CIAT) in Colombia, conserves 4,947 landraces from 27 different countries. These landraces, selected over thousands of years, are a premier source for novel alleles conferring abiotic stress tolerance. To support a fast and cost-effective deployment of climate-adaptive alleles from the CIAT collection, 3,050 cassava landraces with geographic coordinates were used to extract variables characterizing the climate at their collection sites for an environmental Genome-Wide Association Study (EnvGWAS)
