Abstract
Estimates of phenotypic and genotypic variances for some vegetative and yield traits in the oil palm (Elaeis guineensis Jacq.) were obtained from a progeny trial consisting of 13 hybrids from the first backcross generation (BC1) of the F1 interspecific hybrid (Elaeis oleifera x E. guineensis) crossed to E. guineensis and an F1 interspecific hybrid. The parameters were used to construct selection indices for high yield at peak production stage. The result showed that early yields, usually the second and third years of production singly or in combination with one or two traits, could be used to select for oil palm genotypes that would be high yielding at maturity. This implies that a breeding cycle of 7 to 8 years would be sufficient for efficient selection for higher productivity in the oil palm.
