Future crops need to be sustainable in the face of climate change. Modern barley varieties have suffered genetic erosion, losing genetic diversity and becoming vulnerable to climate change. Utilizing diversity in landrace populations, combined with information about local environmental and climatic conditions, allows targeted selection of key traits and genotypes, enabling crop production in marginal soils. Genomics technologies and big data can be used to support sustainable agriculture through germplasm development from landrace collections.
Future crops need to be sustainable in the face of climate change. Modern barley varieties have been bred for high productivity and quality; however, they have suffered considerable genetic erosion, losing crucial genetic diversity. This renders modern cultivars vulnerable to climate change and stressful environments. We highlight the potential to tailor crops to a specific environment by utilising diversity inherent in an adapted landrace population. Tapping into natural biodiversity, while incorporating information about local environmental and climatic conditions, allows targeting of key traits and genotypes, enabling crop production in marginal soils. We outline future directions for the utilisation of genetic resources maintained in landrace collections to support sustainable agriculture through germplasm development via the use of genomics technologies and big data.
