Resumo

The objective of this research was to evaluate the genetic variation and estimate genetic parameters of growth of Hancornia speciosa Gomes plants that constitute the EA/UFG Germplasm Collection, including 28 populations of four botanical varieties. Plant height and stem diameter were evaluated, which resulted in 20 measures that were transformed into growth rate. Mangaba tree progenies present high levels of genetic variation in stem diameter and plant height and to their growth rates. For stem diameter, most of the genetic variation within populations and for plant height it was among populations. The botanical varieties cuyabensis and gardneri had better growth rates, both in stem diameter and in plant height.
