Intra-varietal diversity in cv. ‘Tempranillo Tinto’: phenological stages

Abstract

‘Tempranillo Tinto’ is one of the most relevant grapevine cultivars worldwide. Despite its early ripening and relatively short vegetative cycle, which may not be ideal for high-quality grape and wine production in warming conditions, its long-standing cultivation has led to an intense multiplication by cuttings, which originated the high level of clonal variation currently available. Now, this intra-varietal diversity provides an interesting opportunity for cultivar improvement by identifying genotypes with better adaptation potential.
To explore this potential, we conducted a comprehensive study on 30 ‘Tempranillo Tinto’ clones, chosen from a wide selection of 729 clones in the Rioja winemaking region of Spain. The focus was on characterizing four key phenological stages (budburst, full flowering, veraison, and harvest), for each clone over three consecutive seasons (2020-2022). Results revealed substantial differences among the studied clones, particularly in the duration of their vegetative cycle. Thus, whilst some early clones reached full maturity as early as September, others needed to be harvested at the end of the same month. The most significant difference among clones was observed in the interval between veraison and harvest dates, varying by up to 27 days. In conclusion, our findings suggest that clonal diversity in phenological traits can be an effective strategy to address varietal limitations towards climate conditions. This approach allows for the preservation of the typicity and added value conferred by ancient elite varieties in traditional winemaking regions, without the necessity of switching cultivars.

Exploring the use of high-power ultrasound in white and rosé winemaking

Since the approval in 2019 of the use of high-power ultrasound (US) in winemaking to support extractive processes from grape to must, the study of this technology in red winemaking has increased significantly, with laboratory and semi-industrial scale studies.

Exploring intra-vineyard variability with sensor- and molecular-based approaches 

The application of remote and proximal sensing is a fast and efficient method to monitor grapevine vegetative and physiological parameters and is considered valuable to derive information on associated yield and quality traits in the vineyard. Further details can be obtained by the application of molecular analysis at the gene expression level aiming at elucidating how pathways controlling the formation of different grape quality traits are influenced by spatial variability. This work aims at evaluating intra-vineyard variability in grape composition at harvest and at comparing this with remotely sensed canopy vegetation data and molecular-based approaches.

Unveiling the Grapevine Red Blotch Virus (GRBV) host-pathogen arms-race via multi-omics for enhanced viral defense 

The Grapevine Red Blotch Virus (GRBV) poses a critical challenge to the wine sector, lacking a uniquely identified vector. Current control methods involve costly and labor-intensive vine removal, emphasizing the urgency for targeted alternatives. The limited understanding of intricate host-virus interactions underscores the need for foundational knowledge to develop innovative disease control strategies. These include efforts to boost the plant’s RNA interference (RNAi) response, including RNA-based topical applications.
