Resumo: 	This work aimed at estimating genetic parameters from the vegetative stage in five populations from Jatropha curcas L. The half sib progenies were cultivated at Biojan farm, in Janaúba, MG. Plant height, stem diameter, number of branches and crown projection were assessed in all plants at three and six months old. In population 2, there was no genetic variability for all traits evaluated. The genetic gains estimated with the selection from the ten best individuals in other populations were 4% to 8% for plant height (population 1 and 4), 5% to 7% for stem diameter (population 1 and 5), 14% to 25% for the number or branches (population 3 and 5) and 9% for crown projections in population 4. According to the results obtained from this study, these populations are adequate for the continuity of the breeding program of this species in the region.doi: 10.4336/2010.pfb.30.61.25
