Bamboo plantation has gained great attention in Brazil due to its useful production provided to the society and the ecological,
economic, social and cultural functions of these plantations. For the establishment of high productivity plantations, evaluation of
germplasm and selection of superior genotypes is necessary. This work aimed at early evaluation of the genetic parameters of
potential bamboo species for planting in Brasília/DF. For this purpose, a clonal test consisting of seven species was established:
Bambusa oldhamii, Bambusa vulgaris, Bambusa vulgaris var. vittata, Dendrocalamus asper, Dendrocalamus latiflorus, Guadua
angustifolia and Guadua chacoensis. The experiment was planted in a completely randomized block design, with three replications
and fifteen plants per plot. At 360 days after planting, all individuals were evaluated for their characteristics: height of aerial part,
number of sprouts, clump base area, clump coverage area and density of stalks per clump. The statistical analyses were carried out
through the procedure of mixed models: Maximum Residual Likelihood/Better Non-Victimised Linear Prediction. There were
significant species effects on the characteristics of the aerial part height and number of shoots, as well as high estimates of selective
accuracies. Genetic parameters and genotypic values demonstrate genetic variability between species and the possibility of future
gains from selection. New evaluations will be carried out annually to aim a greater knowledge of the behavior of germplasms at
different ages. At the age of five (commercial court), the best genotypes will be selected for the experimental environmental
conditions.
