Genome Editing and Integrative Breeding Strategies for Climate-Resilient Grapevines and Sustainable Viticulture

Climate change introduces a critical threat to global viticulture, compromising grape yield, quality, and the long-term sustainability of Vitis vinifera cultivation. Addressing these challenges requires innovative strategies to enhance grapevine resilience. The integration of multi-omics data, predictive breeding, and physiological insights into ripening and stress responses is refining our understanding of grapevine adaptation mechanisms. In parallel, recent advances in plant biotechnology have accelerated progress from marker-assisted and genomic selection to targeted genome editing, with CRISPR/Cas systems and other New Genomic Techniques (NGTs) offering advanced precision tools for sustainable improvement. This review synthesizes the major achievements in grapevine genetic improvement over time, tracing the evolution of strategies from traditional breeding to modern genome editing technologies. Overall, we highlight how combining genetics, biotechnology, and physiology is reshaping grapevine breeding towards more sustainable viticulture. The convergence of these disciplines establishes a new integrated framework for developing resilient, climate-adapted grapevines that maintain yield and quality while preserving varietal identity in the face of environmental change.
