Within the scope of the project GEniuS we want to evaluate the possibility of shortening the generation time of silphium by 50% in order to achieve faster breeding successes. The shortened generation time will be achieved once by the in vitro culture of immature embryos and thereby shortening the long seed maturity and germination period of the seedlings. Furthermore, the normally 4–5 months of natural hibernation should be drastically reduced by the accelerated growing in the greenhouse.The project aims to phenotyping a unique collection of new genotypes from across the hole natural range of Silphium perfoliatum. These accessions should be used for initial advances in breeding. Genetically, these new genotypes are completely different from the material used in Germany for cup plant projects before. Within the new genotypes, a new interesting phenotype has been discovered. In case of those phenotype the plants developed normal petioles, which means that water is not able to accumulate in the leaf axils anymore. This phenotype of the cupless cup plant should be analyzed in terms of its inheritance, so that it can be used and selectively crossed in the future. The aim will be to be to develop by the way more stable and due to the lower water content in the field more healthier plant material. Based on this innovative and unique collection, the applicants propose the implementation of the GEniuS project. Due to the project the Federal Republic of Germany will be furthermore capture a leading position in research of Silphium and can even significantly expand it. In the long term, the research for improved cup plant material will be lead to a significantly increased and more sustainable demand for this ecologically valuable crop. This should further increase cultivation of those crop. The proposed project will make a valuable contribution to the wider cultivation of perennial crops, which should positively support the sustainability objectives of the Federal Republic of.
