The objectives of this work were to estimate the phenotypic and genetic parameters and genetic gains for charcoal properties, as well as to select Eucalyptus clones on the basis of charcoal characteristics. A total of nine Eucalyptus clones, cultivated in the region of Taiobeiras, Northern Minas Gerais, Brazil, were analyzed. Three-meter logs were used for specimen preparation. The experiment was arranged in a complete randomized design, with three repetitions. The phenotypic and genetic parameters were estimated using the expected mean squares. The genetic gain was estimated for the characteristics showing significant differences. The clone effect was significant for charcoal yield, carbon yield and apparent relative density. The obtained genetic gain predicted for charcoal yield was 4.51% when the clones FGA-30 and FGA-49 were selected, and 4.16% for carbon yield when the clones FGA-30 e I-249 were selected. The genetic gain was 0.03% for relative apparent density, for the selection of the clones FGA-49 e FGA-34.
