Furthermore, land used for rubber production is being converted[by whom?] Dandelion Rubber from Continental Nominated as One of the Top 3 Projects at the GreenTec Awards 2014. The discovery of Russian dandelion. kok-saghyz. But none seem to produce as much as the Russian dandelion or contain as strong a rubber. In the 1930s, Russia experimented with making rubber from dandelion roots but abandoned the project after the war. Indigenous to the high plateau of south-east Kazakhstan, and the adjacent areas of China and Kyrgyzstan, the Russian dandelion produces a high quality of natural rubber … [5], Taraxacum kok-saghyz is a perennial plant with a yellow composite flower characteristic of the genus Taraxacum. Despite its potential to help maintain a stable worldwide rubber supply, little is known about genetic variation in this species. [9], Researchers have started to develop Taraxacum kok-saghyz cultivars which are easier to cultivate and which produce more and better rubber as part of a large research project at many institutions. [citation needed] Its latex was traditionally used as a kind of chewing gum. The other good option for rubber, Russian or Kazak dandelion (Taraxacum koksaghyz), is a fast-growing plant with a high-quality rubber that was discovered in 1931 in Kazakhstan . It is easier to cultivate and delivers rubber faster. Russian Dandelion and Guayule have almost identical qualities compared to natural rubber harvested from the Hevea tree, which is currently the primary source for the natural rubber used in tires. Attention on T. kok-saghyz has revived due to allergic reactions to Hevea rubber used in medical devices, and to shortcomings in the supply of rubber from Hevea brasiliensis. Rodin (n.d.) confirmed that TKS is a simple perennial which typically grows to a height of 30cm. [2][4], Kok-saghyz is derived from the Kazakh kök-sağız (көк-сағыз), with kök meaning green and saghyz meaning rubber or gum. Russian dandelion has qualities very similar to those of natural rubber harvested from the Hevea tree, which currently is the main source of natural rubber used in tires. Taraxacum kok-saghyz, often abbreviated as TKS and commonly referred to as the Kazakh dandelion, rubber root, or Russian dandelion, is a species of dandelion native to Kazakhstan, Kirghizia and Uzbekistan, that is notable for its production of high quality rubber. OSU's research on making rubber from the Russian dandelion was a continuation of work done by a Russian university, Milewski said. “We are very pleased to receive this award,” said Dr Carla Recker, who heads the development project for obtaining natural rubber from dandelions at Continental. [4][2] In May 2019 German tire-maker Continental AG announced it was about to begin production of the "first bicycle tyre made with sustainable rubber from dandelions", which it intended to grow on the grounds of its own manufacturing plants, avoiding several of the traditional issues with H. brasiliensis latex—from the long lead-time between planting and cultivating (only six months for the dandelion, rather than seven years for the rubber tree) and volatile prices of the product due to the long transport-distances between places where the rubber can be grown and the company's factories. Ford got involved after a local Ford car dealer near OSU, who knew about the company's other bio-materials work, heard about the project and wrote to Executive Chairman Bill Ford about it, she said. Compra Farmerly Russian Dandelion/Kazakh Dandelion/Rubber Root (Taraxacum Kok-Saghyz) Seeds (~50): Non-GMO, Certified Organic Heirloom Seed Packet. Russian dandelion, or TKS was cultivated on a large scale in the Soviet Union between 1931 and 1950. Also known as Kazakh dandelion or rubber root, Russian dandelion resembles the familiar dandelion, but the leaves are thicker and have a grayish tint. TKS can be Rubber Root, alternately known as Russian or Kazakh Dandelion (Taraxacum kok-saghyz) is a perennial dandelion with origins in the Kazakhstan / Uzbekistan regions.The plants are smaller than Taraxacum officinale and Taraxacum albidum (two other varieties we offer in our catalog), with thicker and a paler greens. Rubber from Russian dandelions: a serious European alternative to rubber tree plantations Published on June 19, 2016. Because of the invention of synthetic rubber and the higher yields of rubber per hectare from the rubber tree, the dandelion was mostly forgotten. [6] Plants may contain 25 to 50 leaves arranged in one or more rosettes at the upper end of the root. Although natural rubber is found in at least 2,500 plant varieties, most of these are unsuitable for the large-scale production of good quality rubber. The roots of this dandelion species contain the natural rubber latex (the source for natural rubber used in tires), meaning supply will be steadier and easier to control leading to greater price stability. Taraxacum kok-saghyz, often abbreviated as TKS and commonly referred to as the Kazakh dandelion, rubber root, or Russian dandelion,[1][2] is a species of dandelion native to Kazakhstan, Kirghizia and Uzbekistan, that is notable for its production of high quality rubber. Russia. Russian dandelion (Taraxacum kok-saghyz) proofed to be a suitable replacement for natural rubber in the production of high-quality rubber products such as tyres. The Soviet Union cultivated Taraxacum kok-saghyz, together with Taraxacum hybernum [ru] and Scorzonera tau-saghyz, on a large scale between 1931 and 1950—notably during World War II—as an emergency source of rubber when supplies of rubber from Hevea brasiliensis in Southeast Asia were threatened. Since dandelions are only of limited use as a wild plant for agricultural production, plant breeders clarify the physiology of rubber synthesis and develop suitable varieties for successful industrialization. The discovery of Russian dandelion. Rubber Root, alternately known as Russian or Kazakh Dandelion (Taraxacum kok-saghyz) is a perennial dandelion with origins in the Kazakhstan / Uzbekistan regions.The plants are smaller than Taraxacum officinale and Taraxacum albidum (two other varieties we offer in our catalog), with thicker and a paler greens. Using its proprietary selection techniques, KeyGene develops high performing varieties of rubber dandelion: from a small weed to a real crop. Nearly all this rubber currently has its origins in rubber tree plantations in Asia. To achieve this, together with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME, ESKUSA GmbH and hortilab, ecSeq Bioinformatics GmbH generated a high-resolution genetic map of Russian dandelion. The cultivation of dandelion also offers the opportunity to increase the diversity of cultivation on domestic fields. This is used to achieve the following breeding objectives: Find more information about the research project and ecSeq's involvement in this information leaflet by the FNR, the central coordinating agency in the area of renewable resources in Germany: Receive updates about NGS articles and trainings.

The United States, the UK, Germany, Sweden and Spain also cultivated the plant for the same reason. Russian dandelion (Taraxacum kok-saghyz) is native to the mountainous regions of Uzbekistan and Kazakhstan. Two plant species have received considerable attention as potential alternative sources of natural rubber: the Mexican shrub Guayule (Parthenium argentatum Gray) and the Russian dandelion (Taraxacum koksaghyz). Russian dandelion . Natural rubber is an indispensible ingredient in tens of thousands of applications, from car and aircraft tyres to medical equipment. “We are making […] crosses between the Russian dandelion and the common dandelion using those modern DNA profiling technologies,” says KeyGene CEO Arjen Van Tunen.
