The present utility model relates to in vitro method of propagating rubber rootstocks via microcutting technique, which involves identifying high yielding rubber clones that are amenable to the propagation methods developed without changing their genetic potential and assessing the field performance of such clones. The method further involves establishing rubber budwood gardens for maintaining rubber clones so as to be assured of an available source of rubber clone explants. The microcutting technique involves inoculating the explants on a sterile medium, maintaining the culture of surviving explants and, after a culture period of usually 4 to 6 weeks, subculturing the surviving explants in appropriate media for propagation of shoots without losing their genetic stability. Repeated subculturing is done in order to increase the number of in vitro grown shoots. Conditioning, rooting, acclimatizing and maintaining the resulting rubber plantlets in safe environment or nursery complete the process.
