Resumo: Eremanthus erythropappus (DC.) MacLeish is a native species, economically appreciated due to its wood and the extraction of essential oil, whose active ingredient is alphabisabolol, but studies on genetic improvement of this species are still scarce. The aim of this study was to evaluate survival, genetic variability and estimate genetic parameters in E. erythropappus progenies in the field at 15, 22 and 30 months of age. The experiment was set up at Fazenda Guapiara, in Aiuruoca, Minas Gerais State, where seedlings of 15 progenies were planted in a randomized block design with five replications and six plants per plot. Plant height evaluations were performed and genetic studies were carried out in the SELEGEN software using the REML/BLUP method. At 30 months, the percentage of seedling survival was evaluated. Significant differences were observed between progenies, and the highest estimates of h2mp (0.48) and Acprog (0.69) were found at 30 months. Therefore, even in the juvenile stage, it was possible to identify genetic variability and analyze its expression over time, which makes it possible to continue studies of genetic improvement of the species.
