Abstract

Crop diversity is an essential resource for global breeding programmes aimed at climate resilience. However, adaptation depends both on whether genetic diversity exists and if it is accessible. Here we consider the biological and social risks of crop adaptation at global and national levels using 1,937 publicly available genotyped and georeferenced accessions of sorghum, a staple crop for subsistence farmers. Accessions were given a future climate resilience score and a genomic adaptive capacity score using genomic estimated adaptive values generated from environmental genomic selection. We identified the best potential parents and the geographies that harbour the most promising genotypes for crop improvements, as well as more at-risk areas. Such methods may be expanded to other crops and used for decision support for future breeding. Adapting agriculture to future climate conditions will necessitate increased accessibility to plant genetic resources and their genetic characterization.
