Abstract The Eucalyptus breeding program of URPPI (a partnership between CIRAD-Forêt, Centre National de la Recherche Forestière du Congo, and Unité d’Aforestation Industrielle du Congo) consists of a reciprocal recurrent selection scheme developed in the Congo between the two species Eucalyptus urophylla and Eucalyptus grandis. Two approaches are proposed in order to model and predict the specific combining ability (SCA) between these species. The clustering approach uses a simultaneous clustering procedure of the two species based on SCA and reveals heterotic groups coherent with the geographical origins of E. urophylla genotypes. The second approach uses a multiplicative model to partition the SCA into three multiplicative terms explaining 95% of the interaction.
