Conteúdo: | The aim of this study was to estimate genetic parametersvia mixed models and simultaneously to select Jatropha progenies grownin three regions of Brazil that meet high adaptability and stability. From aprevious phenotypic selection, three progeny tests were installed in 2008 in the municipalities of Planaltina-DF (Midwest), Nova Porteirinha-MG (Southeast), and Pelotas-RS (South). We evaluated 18 families ofhalf-sib in a randomized block design with three replications. Geneticparameters were estimated using restricted maximum likelihood/bestlinear unbiased prediction. Selection was based on the harmonic meanof the relative performance of genetic values method in three strategiesconsidering: 1) performance in each environment (with interactioneffect); 2) performance in each environment (with interaction effect);and 3) simultaneous selection for grain yield, stability and adaptability.
