Résumé : Early selection in rubber tree breeding is made in two successive stages. The seedlings issued from the hand pollination campaign are first assessed in the nursery and then the best genotypes are budded and the clones assessed in a small-scale trial. This two stage selection strategy implies a search for optimization so as to obtain the highest possible genetic gain. Theoretical considerations as well as some results issued from the practice of the rubber breeding programme in Ivory Coast are presented here. In order to get an accurate estimation of the genetic worth of genotypes, the systematic introduction of family structures into the small-scale design is suggested.
