Institut für Rebenzüchtung
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 conditions and the vines can therefore not be evaluated for the desired traits every year. Environment-independent high-throughput phenotyping methods allow breeding material, biparental populations and genetic resources of the Geilweilerhof to be examined continuously. New phenotyping methods and prediction models must be developed and validated for this purpose. The plant material will be phenotyped using sensor-based methods and the objective trait data will be used to evaluate (statistics) and predict (using artificial intelligence) key properties of resistance to biotic and abiotic stress. The comprehensive phenotypic data will also be used for the development of new molecular markers (marker-assisted selection - MAS) in order to increase the efficiency of grapevine breeding with regard to the challenges posed by climate change.
