dc.description.abstractImproper exploitation of native woods have led to a reduction in natural populations, as was the case of Myracrodruon urundeuva. The objectives of this study were to estimate genetic parameters for silvicultural traits in progenies test of M. urundeuva, in multi-species system and evaluate the potential for ex situ conservation and transformation into an orchard seedling seed. The experiment was installed in Selvoria-MS in a randomized block design, with 30 progenies, 14 replications and one plant per plot. The traits were evaluated at four and nine years old and estimates of genetic parameters were obtained by REML/BLUP procedure. The selection for diameter at breast height was based on the combined selection of multi-effect index and genetic values individual additives. Appropriate estimates of genetic variation were obtained (> 12%), average heritability progenies (> 0.35) and accuracy (> 58%). The strategy without restriction of the 180 best individuals provided the highest gain selection (7.48%). Genetic diversity (67%) and effective size (similar to 60) were similar strategy with restriction of individuals and progenies. As a result, the strategy without restriction seemed to be more appropriate. Thus, there is genetic variability in the test M. urundeuva progenies and potential for its transformation into an orchard seedling seed.en
