Résumé : Hevea is an exclusive source of natural rubber. The homogeneity and productivity of hevea plantations are reduced not only by the genetic heterogeneity of seed stocks but also by the physiological ageing of the stocks of selected genotypes. Somatic embryogenesis is used for the rapid and reliable multiplication of these genotypes. The rejuvenation of plant material and the cloning of the whole tree should enhance vigour and increase the homogeneity of plantations. Different lines of "embryogenic calli" (cells kept proliferating in a suitable culture medium) from the PB 260 genotype were used in the experimental production of 20,000 vitroplants between 1996 and 2000. The process is now being adapted to other selected genotypes. Since 1992, field trials have been conducted regularly at five sites (Africa, Asia, Latin America) to measure the growth, production and evaluate other agronomic characteristics of this new plantation material.
