Conteúdo: | Oil palm has stood out among the promising species for biofuel production and plant improvementthrough cloning superior individuals is the technology that contributes most to increase oil production.However, there are no studies on the genotypes behavior regarding both in vitro performance and yieldpotential simultaneously. By this mean, the objective of this paper was to study the genetic control ofthe related characteristics to the oil palm cloning process, and to identify responsive genotypes withina collection of 32 elite materials of a commercial planting in order to select the superior genotypes forthe formation of a clonal garden. Callogenesis and production of embryogenic lines, which are maincharacteristics related to the cloning process, presented genetic control, verified through estimates ofgenetic parameters: heritability, coefficient of relative variation, and selective accuracy; also indicatingefficiency in the selection of superior genotypes within the evaluated set. Genotypes A-13, A-14, A-18,A-20 and A-21 were selected as superior genotypes for both characteristics, such as oil yield and in vitroperformance, due to formation of embryogenic lines. This has been the first study investigating the geneticcontrol of the cloning capacity aiming to the selection of genotypes for a clonal garden formation.
