In Germany and Europe the efficiente cultivation of rape is strongly endangered by harmful insects. In order to secure the cultivation of oilseed rape in the long term, work has begun on developing the genetic basis for breeding insect resistance using the example of pollen beetle (RGK) Brassicogethes aeneus. RGK-resistant accessions of Barbarea vulgaris var. arcanta were identified in the CHEMOEKORAPS project. Based on the CHEMOEKORAPS project, phenotyping of different B. vulgaris accessions and related Barbarea species will be performed on plant material. Secondary plant metabolites (metabolome analyses) will be compared and their deterrent bioactivity in effect dose relationships (bioassays) against the RGK will be determined. The project provides new deterrents and helps to elucidate the resistance mechanism of the chemical defense in B. vulgaris. Results from this project show new plant genetic sources for the breeding of insect-resistant oilseed rape lines and thus contribute to a sustainable and integrated agriculture.
