Intergeneric transfer of chemo ecological mediated resistance against the pollen beetle Brassicogethes aeneus in oilseed rape - Part 2 (CHEMOEKOTRANS)
Project
Project code: 2219NR153
Contract period: 01.03.2020
- 28.02.2023
Budget: 551,013 Euro
Purpose of research: Applied research
Keywords: rapeseed, animal pests, plant health, metabolomics, renewable ressources
Rapeseed cropping in Germany and the EU is strongly endangered by the growing damage caused by different pests. The reduced availability of chemical control means adds to this situation and leads to a declining cropping area of oilseed rape. To ensure rapeseed cropping research projects aiming at novel breeding opportunities for improved insect resistance have been initiated. As a first target in CHEMOEKORAPS resistance against pollen beetles (RGK, Brassicogethes aeneus) has been identified in closely related species, Sinapis alba and Eruca sativa. As a follow-up the project CHEMOEKOTRANS will be starting with the introgression of of RGK resistance and will develop the preconditions for a successful transfer between S. alba or E. sativa and rapeseed. In subproject 1 (Intergeneric Transfer) crosses between S. alba/ E. sativa and B. napus will be made, which will be supported by embryo rescue means and GISH to highlight the introgressed genome. Mapping populations will be generated to allow genetic studies of RGK resistance, marker development and to support the identification of its metabolic basis. In subproject 2 (Chemically/ ecologically mediated resistance) phenotyping of the metabolome and feeding resistance in plant material from subproject 1 will be realized to reveal the causal basis of RGK resistance and deliver different types of markers (molecular, biochemical). Segregating populations will allow to proof correlations between metabolites, markers and resistance. CHEMOEKOTRANS will deliver novel plant material for resistance breeding, molecular and biochemical markers that will support the breeding process. It will contribute major steps towards insect resistant oilseed rape and thereby helps to increase the sustainability of agriculture and integrated pest management.
