Depending on weather conditions, diseases such as, B. lactucae and G. cichoracearum, as well as the aphid N. ribisnigri, which specializes in lettuce, occur on lettuce (Lactuca sativa). These cannot be controlled in organic farming by products of synthetic chemical pesticides and therefore point to the need to optimize plant resistance in organic farming. Interaction with beneficial microorganisms (MO) offers one possibility for this. Accordingly, the objective of this project is to increase the resilience of lettuce to biotic and abiotic stressors. We will identify lettuce cultivars with good responsiveness to beneficial MO (priming effects). The basis of the work planned here will be field experiments in which 30 diverse Lactuca lettuces, including reference cultivars, will be characterized with respect to microbiome and resilience. All work will be in accordance with organic cultivation methods.
