Biotechnology and development of rubber planting material
Breeding and dissemination of planting material for rubber plantations are closely linked to propagation methods. Since the progress made by switching from multiplication by seed to propagation by budding, the development of new techniques, such as micropropagation, has been awaited. Microcuttings was developed from juvenile seedling material and rejuvenated clonal material by reiterated grafting on young seedling or somatic embryogenesis. Somatic embryogenesis procedures were developed on 18 clones worldwide but researches are still needed for large-scale propagation by this method. Both zygotic and somatic embryogenesis allows rejuvenation of plant material, which offers development of new propagation strategies. Thanks to a combination of in vitro culture methods, a whole raft of innovations will be released in the next twenty years for the propagation of higher-yielding planting material. Among those innovations, the establishment of a new generation of so-called juvenile budwood gardens is a possibility within the next five years. That transfer will be decisive for assessing the degree to which new technologies are taken on board in modern rubber growing. The involvement of growers and agro-industrialists upstream of the innovation process is decisive for the success of such an undertaking.
