Special Issue Information

Dear Colleagues,

The conservation and characterization of genetic resources within the Vitis genus form the basis of actions developed in germplasm banks. According to the Vitis International Variety Catalogue (VIVC: www.vivc.de), there are 253 holding institutions worldwide that maintain Vitis plant material. The genetic diversity conserved ex situ in these institutions could be used to breed and certify new plant material, while focusing on developing a more sustainable viticulture. These genetic resources could allow the viticultural sector to mitigate the adverse effects of climate change on cultivation conditions and/or meet to evolve consumers demands.

Therefore, in the last decade, there has been a special interest in promoting new lines of work in plant breeding programs to develop interspecific hybrids with resistance or tolerance to abiotic stresses, pests and disease, and the selection of varieties and clones of Vitis vinifera with greater resilience or ability to adapt to the effects of climate change.

The objective of this Special Issue is to compile all the genetic breeding work on Vitis plants in progress at the present time. We encourage submissions of studies that focus on the identification, agronomic, physiological, and oenological characterization of new and local grapevine varieties, rootstocks, clones, and interspecific hybrids. These studies should emphasize the utilization of these genetic resources to address the challenges facing viticulture and oenology.

Plant genetic resources are increasingly viewed as a key tool to address the multiple challenges faced by modern viticulture. In this context, local grape cultivars are proposed as a strategy to enhance resilience to climate change and to diversify wine styles. However, while genetic identification has been widely reported, field-based phenotyping information for local cultivars under current climate conditions remains limited. In this context, phenotyping results are presented for six local Andalusian cultivars (Castellano, Beba, Cañocazo, Mantúo de Pilas, Perruno and Vigiriega). All cultivars were grown in a vineyard plot in the Marco de Jerez and evaluated over three consecutive seasons (2023–2025). Morphology was assessed using 46 descriptors, allowing cultivars to be grouped into two main clusters. Phenological monitoring showed a measurable year effect while preserving a consistent relative ranking among cultivars, most clearly during veraison and ripening, with Castellano reaching these stages earlier and Mantúo de Pilas later. Grape must composition highlighted contrasting ripening dynamics, with Palomino Fino and Castellano generally reaching higher sugar levels, whereas Vigiriega and Mantúo de Pilas showed the most acidic profiles. These results provide growers with performance-based comparative information to support cultivar selection for new plantings and to explore the potential of local cultivars for developing new wine styles under warm climate conditions.

Historically, certain physiological behaviours were typically attributed to genetic factors. However, some grape varieties exhibit different responses depending on crop management and environmental conditions. The present study examines whether the physiological responses of grapevines traditionally attributed to genotypic traits (near-isohydric or near-anisohydric behaviour) can instead be substantially modified by canopy architecture. The objective was to determine how canopy management influences water relations (leaf water potential—ΨL), physiological plant responses (water use efficiency (WUE), stomatal conductance (gs), transpiration (E) and photosynthetic (A) rates), and radiation interception efficiency (εi), particularly under warm Mediterranean conditions. To test this, two training systems were evaluated in a Syrah vineyard: a vertical shoot position (VSP1) and a sprawl (S1) system with 12 shoots·m−1, under the same irrigation regime. The results showed that under stressed conditions (high vapor pressure deficit [VPD] and relatively lower ΨL, from −1.4 to −0.6 MPa), the S1 system—despite a similar leaf area index, LAI—exhibited lower gs values than those of the VSP1 system (10–30%), with plants closing their stomata to reduce water consumption and prevent their dehydration caused by steep E rates. Meanwhile, the VSP vines exhibited higher gs values (isohydric-like response), indicating higher E rates, which reduced their WUE and intrinsic water-use efficiency (IE). This strategy (similar to the anisohydric one) allowed the S1 treatment to obtain higher WUE and interception radiation efficiency (εi) ratios, even at low ΨL (more efficient), produced by the higher canopy demand (more exposed surface area [SA]). These contrasting behaviours indicate that sprawl systems can enhance radiation interception and WUE compared with vertical systems under semiarid Mediterranean conditions. Full article

This study examined clonal variation in Vitis vinifera L. cv. ‘Merzifon Karası’, a Turkish wine grape. Thirty-two clones were evaluated for key growth and enological characteristics, including cluster structure, berry attributes, yield components, millerandage index, and berry skin color. Considerable variability was observed in cluster weight (95.8–254.1 g), berry weight (0.64–3.06 g), and millerandage index (1.35–9.77), highlighting the importance of clonal selection for optimizing fruit set, cluster compactness, and overall vineyard performance. Promising clones, such as F13/29, K11/27, and H20/24, combined high yield, well-formed clusters, and low millerandage indices, whereas clone K13/10 exhibited exceptional uniformity in fruit set, achieving the lowest millerandage index. Incorporating berry skin color characteristics further identified K11/27, F13/29, and K13/10 as particularly favorable for both productivity and winemaking quality due to their dark berries, consistent fruit set, and well-formed clusters. These findings illustrate the potential of targeted clonal selection to enhance sustainable viticulture and improve fruit quality in ‘Merzifon Karası’. Full article
