Sensor-based high-throughput evaluation of breeding material in the field
One of the tasks of grapevine breeding is to contribute to the preservation of viticultural cultural landscapes by developing robust and climate-adapted varieties. New grape varieties must have a strong resistance to pathogens, pests, and abiotic...
Term: 2025-01-01 bis 2029-12-31Improving efficiency in grapevine breeding using an AI-supported high-throughput phenotyping pipeline to select for resilience to abiotic and biotic stressors
One of the tasks of grapevine breeding is to contribute to the preservation of viticultural cultural landscapes by developing robust and climate-adapted varieties. New grape varieties must have a strong resistance to pathogens, pests, and abiotic...
Term: 2025-05-01 bis 2027-04-30Environment-independent investigation of phenotypic characteristics linked to grapevine’s resilience towards biotic and abiotic stresses
The project aims to identify and investigate phenotypic traits that increase the resistance of vines to biotic and abiotic stressors such as grape botrytis and sunburn. The occurrence of these stressors in the field depends on the environmental...
Term: 2025-01-01 bis 2029-12-31Healthy grapevines (Vitis vinifera) in organic viticulture by means of research, innovation and transfer
In viticulture, considerable amounts of fungicides are used for the control of introduced fungal diseases. Especially for organic viticulture, downy mildew, caused by Plasmopara viticola, is a major problem. Rainy weather periods, which may occur...
Term: 2019-06-17 bis 2025-12-31Vitis Leaf Hair - A new functional trait for sustainable and climate-adapted viticulture - Subproject B
In contrast to the almost hairless cultivated vine (V. vinifera), certain Vitis species have very densely hairy leaf undersides. Dense leaf hairs hinders the entry of Plasmopara viticola spores into the leaf stomata and reduces water loss through...
Term: 2025-05-15 bis 2029-05-14Knowledge-based measures for sustainable crop protection for long-term maintenance of peronospora resistance in fungus-resistant grapevine cultivars
Leaves with fresh infections of P. viticola will be collected from geographically diverse vineyards of PIWI cultivars at different phenological stages. These isolates are first subjected to basic genetic and phenotypic characterization. Particularly...
Term: 2024-06-01 bis 2027-05-31Grapevine breeding for integrated pest management
ZR is involved in the development of markers and their validation for marker-assisted selection (MAS) to increase breeding efficiency for resistance to black rot and Botrytis (berry skin permeability). Candidate genes for resistance will be proposed...
Term: 2024-04-01 bis 2028-03-31Strategies for resilient grapevines in a changing climate
In a first step, promising PIWI varieties from project partners of Switzerland, Alsace, Rhineland-Palatinate and Baden as well as breeding material from collaborated breeders with high berry skin stability will be selected. Therefore, berry traits...
Term: 2023-10-01 bis 2026-09-30Improving the selection of climate-resilient grapevine varieties
In preliminary work, plant material was prepared and initial molecular data was collected, which is to be evaluated as part of the project. Two different sets of starting material, which were sequenced with approx. 8x Illumina, are available for the...
Term: 2024-04-01 bis 2027-03-31Predictive Breeding for Wine Quality (Phase 3)
Evaluation of new grapevine cultivars regarding their quality potential is the time limiting factor during grapevine breeding. »SelWineQ« aims at developing robust models and tools to predict wine quality on a genetic and molecular level, leading...
