Comparative analysis of infection and defensive strategies associated with powdery mildew disease in grapevine and strawberry
Domesticated strawberry and grape are fruits of very significant commercial and nutritional importance worldwide.
The XIVth International Symposium on Grapevine Breeding and Genetics is held in Zagreb (Croatia) from June 28 to July 2, 2026.
The event is organised by the Faculty of Agriculture, University of Zagreb in collaboration with Institute for Adriatic Crops and Karst Reclamation Split, Institute of Agriculture and Tourism Poreč, Faculty of Agrobiotechnical Sciences Osijek.
Domesticated strawberry and grape are fruits of very significant commercial and nutritional importance worldwide.
Downy mildew caused by Plasmopara viticola remains a central challenge in grapevine production, particularly under conditions aiming at reduced fungicide input.
Pest- and disease-resistant rootstocks are foundational to sustainable global viticulture, offering a strategy to mitigate edaphic stressors and climatic variability while optimizing scion performance.
The study was conducted using 9 fungal-resistant varieties planted at the “Finca Valdegón,” belonging to the Government of La Rioja.
The fungus Erysiphe necator causes powdery mildew (PM), one of the most significant diseases of grapevine.
Grapevine virus A(GVA), a member of the genus Vitivirus (family Betaflexiviridae), is an economically important pathogen associated with grapevine wood diseases and significant yield losses.
Grapevine production in the EU faces increasing pressure from climate change, high pesticide dependence, and the need to maintain grape and wine quality while reducing environmental impact.
Grapevine leafroll-associated virus 3 (GLRaV-3) represents a significant threat to viticultural productivity.
As other vegetatively-propagated species, grapevine (Vitis vinifera L.) can be subjected to contamination, throughout the multiplication cycles, with a number of pathogenic agents, including viroids and viruses.
Intra-varietal diversity has been widely studied to improve the adaptability of Vitis vinifera cultivars to climate change, which is altering cultivation conditions, agricultural practices and suitable growing areas.
