Abstract : The study presented in this paper consisted of three comparisons between the performances of 23 clones evaluated in five clonal trials and their performances as progenitors in three progeny trials in Côte d'Ivoire, for yield, vigour and yield efficiency. Some significant correlations were observed in the case of two of the three progeny trials, but the sense of the correlations changed according to the genotypes under study, making the results inconclusive. Additional studies should be carried out, with much larger numbers of genotypes and in different environments, in order to obtain a clear appreciation of the possible use of clone values to predict combining ability.
