Interpretive Summary: Like they did for the green revolution last century, worldwide genebanks can confer phenotypic and genetic novelty useful to increase yield and crop adaptability. However, new strategies for genebank utilization must be empowered to meet the increasing global food demand. This review article compiles major recent ‘big data’ developments that are likely to enhance the identification, conservation, and use of crop genetic resources for the development of better-adapted crop varieties.

Technical Abstract: Crop wild relatives and landraces harbor unique variations that may prove useful for climate change adaptation. Yet, their factual utilization has been hampered by poor characterizations, incompatibilities and polygenic variance. This editorial review includes the topics of (1) unlocking phenotypic and genetic variation hidden in crop wild relatives and landraces, (2) major challenges to utilize crop wild relatives and landraces to improve complex polygenic adaptive traits, (3) modern experimental (e.g. speed breeding, de novo domestication, genome editing) and analytical (e.g. predictive breeding, genomic selection, machine learning) approaches that could speed up the utilization of wild relatives and landraces within conservation and breeding programs, (4) novel approaches to merge pre- and breeding efforts towards the increase of crop adaptability and yield, (5) strategies to match future global food demands in the face of increased abiotic and biotic stresses, and (6) data compilation, ‘big data’, and database management targeting crop wild relatives and landraces.
