These technologies can provide detailed insights into vineyard conditions, allowing for targeted interventions that minimize environmental impact while maximizing productivity (Keller, 2010). The use of molecular markers and genomic tools in precision viticulture can also facilitate the development of management practices that are tailored to the specific genetic makeup of grapevine varieties, thereby optimizing fruit quality and yield (Massonnet et al., 2019). 8.3 Collaborative efforts in global grapevine genomics Collaborative efforts in global grapevine genomics are essential for advancing the field and addressing the challenges posed by climate change and global market demands. International collaborations can facilitate the sharing of genomic data and resources, enabling researchers to build comprehensive databases that support the development of new grapevine varieties. The establishment of open information systems, such as the GrapeIS, can enhance data accessibility and interoperability, fostering a collaborative research environment that accelerates scientific discovery (Adam-Blondon et al., 2016). These collaborative networks can also support the standardization of genomic tools and methodologies, ensuring that research findings are comparable and reproducible across different studies (Adam-Blondon et al., 2016). By pooling resources and expertise, global collaborations can drive innovation in grapevine genomics, leading to the development of varieties that meet the diverse needs of growers and consumers worldwide (Brault et al., 2021). Such efforts are crucial for ensuring the sustainability and competitiveness of the global grape and wine industries in the face of evolving environmental and economic challenges (Keller, 2010). 9 Concluding Remarks Advancements in genomic technologies have transformed the selection and breeding of grapevine varieties for wine production. The availability of a complete reference genome has fundamentally changed grape breeding by facilitating marker-assisted selection (MAS), which enables breeders to select plants based on genetic markers linked to desirable traits rather than relying solely on phenotypic characteristics. This genomic-driven approach has significantly improved the efficiency of breeding programs, particularly for traits with low heritability or those that are challenging to phenotype. Furthermore, combining genomic selection (GS) with polyploidization has emerged as a promising strategy to develop grapevine genotypes with enhanced attributes, such as superior fruit quality and increased stress tolerance. Precision breeding techniques, incorporating advanced gene insertion and genomic analyses, have also accelerated the development of elite grapevine cultivars with improved agronomic and enological characteristics. Collectively, these genomic advancements provide a foundation for the creation of innovative grapevine varieties that are better adapted to dynamic environmental conditions and evolving market demands. To fully capitalize on these advancements, future research must address several critical areas. First, a thorough exploration and characterization of grapevine germplasm are essential to identify and leverage the genetic diversity within the Vitis genus. This will enable the development of new varieties capable of thriving in diverse environmental conditions. Second, integrating genomic selection with other omics data, such as transcriptomics and metabolomics, will enhance the predictive accuracy of breeding models, accelerating the identification of desirable traits and the breeding process itself. Third, refining genome editing techniques, such as CRISPR/Cas9, is imperative to achieve precise modifications of genes associated with key traits, thereby increasing the efficiency and effectiveness of breeding programs. Finally, challenges related to grapevine regeneration and transformation must be addressed to improve the success rates of genetic modifications. By advancing these research priorities, the field of grapevine breeding can further contribute to sustainable viticulture and the production of high-quality wine, ensuring resilience in the face of climate change and market shifts.
