It is not the domestic dandelion that is grown, but the Russian one. It has a rubber content of between five and ten percent in its milky juice, the latex. Within a short time, breeders were able to rubber content to 15 percent, based on the dry matter of the roots, double. Rubber trees, on the other hand, have a latex content of 25 to 30 percent.
Therefore that is enough dandelion The amount of rubber that can be recovered is not yet sufficient for competitive production. For economically viable use, the aim is to achieve a yield of at least 20 t of fresh root mass per hectare. The researchers want to use crosses with common dandelions, which can form a strong root of up to one meter Biomassage drag and what has already been achieved Stabilize rubber content. The aim of the project is to come as close as possible to achieving economical cultivation.
