The commercialization of cultivation and the large-scale use of Russian dandelion rubber, taking into account possible joint uses, are the overarching objectives of the project consortium. Rapid achievement of economic viability will be possible through building on the success in breeding, agriculture and raw material processing of completed projects, and identified weaknesses will be addressed through targeted exploitation research. The interdisciplinary team consisting of a university, research institutes, breeding and commercialization companies and an additional network of service providers will collaborate in a targeted manner on questions in the fields of breeding, breeding methodology, agronomy of seed production and plant processing. Overall, it aims to improve cultivation through performance breeding and reduce costs in upstream areas, thereby accelerating commercialization. In order to achieve the goals, existing plant material should be further improved as part of the breeding activities, and new methodologies should be derived and applied from investigations on recombination behavior. Here, genome interactions as well as single factors of recombination processes are in focus. The resulting material and the scientific results from breeding methodology and recombination analysis are integrated into the breeding material via a breeding scheme. The work on the agronomy of seed production is aimed at sowing, flowering over several seasons and targeted monitoring of plant populations for persistence and spreading. As breeding activities continue to yield new plant types with altered morphology (e.g. root and leaf mass) that are put to direct use, crop and raw material processing including product characterization must be adjusted. Therefore, rubbers from new breeding material will be assessed.
