Grapevine breeding and germplasm curation require a scalable, cost-effective genotyping solution that performs robustly across wine, table, raisin, juice, and muscadine grapes from diverse Vitis species.
Downy mildew (Plasmopara viticola) and powdery mildew (Erysiphe necator) are among the most destructive diseases affecting grapevine (Vitis vinifera L.).
Completed or ongoing projects were designed to identify, refine, and optimize phenotypic and molecular criteria for genetic improvement and management practices, aiming to reduce the incidence and severity of grape ripe rot (GRR).
Grapevine cultivation is heavily dependent on chemical pesticides to manage biotic or abiotic stressors.
Preserving the genetic heterogeneity of grapevine provides a valuable reservoir of allelic combinations that can offer genetic traits to contrast biotic and abiotic stresses, highly advantageous for breeding programs.
In the past breeding programmes for grapevine varieties for cool climate focused on developing early ripening cultivars that are better adapted to the prevailing climatic conditions.
The value that perennial crop improvement can offer is constrained by the lag between when growers define a problem and when genetic solutions reach the vineyard.
‘White Riesling’ is the flagship grapevine cultivar of the Rheingau region. However, due to climate change, its cultivation faces increasingly challenging conditions, including drought stress, high solar radiation, and heightened pathogen pressure.
Although the grapevine (Vitis spp.) is among the oldest and most economically significant fruit species globally (Candar et al., 2021), its genetic improvement faces major bottlenecks due to long juvenile periods and extended cycles for phenotype evaluation
Freeing seedless table grape producers from paying royalties on patents held by international breeding companies is a primary objective of the breeding programs promoted by the IVC
The cultivation of disease-resistant winegrape varieties (PIWI) is gaining interest worldwide, particularly in viticultural areas where the use of fungicide is limited.
Clonal selection remains central to grapevine improvement, yet consistent yield and fruit quality across vintages are challenged by pronounced genotype-by-environment interactions (G×E).
The climatic conditions of southern Brazil favor the incidence of fungal diseases in grapevines, which hampers the cultivation of Vitis vinifera varieties.
Climate variability and rising biotic pressure threaten global viticulture. Modern wine production depends on a limited number of grapevine cultivars, represented by multiple clones that differ slightly in their agronomic, oenological, or stress-tolerance traits.
Native American muscadine grape (Muscadinia rotundifolia) represents a strategically important reservoir of allelic diversity for grape improvement.
