Zusammenfassung: | The research intends to characterize trees and fruits from natural populations of Hancornia speciosa Gomes, as well as evaluate the distribution of phenotypic variability among them. Populations of mangaba trees were sampled in the Cerrado, including the states of Goias, Tocantins, Mato Grosso, Mato Grosso do Sul, and Bahia, covering 109 mother plants from 35 populations of the botanical varieties pubescens, gardneri, speciosa and cuyabensis. The results showed that the H. speciosa plants have high levels of phenotypic variation in terms of fruit characterization and, on the whole, most of this variation occurs among populations. There is also a large phenotypic variability within the botanical varieties. Hancornia speciosa var. gardneri and H. speciosa var. pubescens fruits are larger and heavier. The botanic variety gardneri shows gait higher than the others varieties. In the varieties gardneri and pubescens predominate round shape and light green color, while in speciosa and cuyabensis predominate oblong shape and dark yellow and dark green colors, respectively. The varieties gardneri and pubescens stand out as the most potential for selection based on the characters of the fruit size and fruit mass. Index terms: mangaba, phenotypic variability, native species. O trabalho objetivou caracterizar arvores e frutos de populacoes naturais de Hancornia speciosa Gomes, bem como avaliar a distribuicao da variabilidade fenotipica existente. Populacoes de mangabeiras foram amostradas no Cerrado, incluindo os Estados de Goias, Tocantins, Mato Grosso, Mato Grosso do Sul e Bahia, abrangendo 109 matrizes de 35 populacoes das variedades botanicas pubescens, gardneri, speciosa e cuyabensis. Os resultados mostraram que, nas condicoes do Cerrado, as matrizes de H. speciosa apresentam elevados niveis de variacao fenotipica quanto a caracteres de frutos, sendo que a maioria dessas variacoes esta entre populacoes. Ha, tambem, uma grande variacao fenotipica dentro das variedades botanicas. Hancornia speciosa var. gardneri e H. speciosa var. pubescens tem frutos maiores e mais pesados. A variedade botanica gardneri apresenta porte mais alto que as demais. Nas variedades gardneri epubescens, predominam frutos redondos e verde-claros, enquanto em speciosa e cuyabensis predominam frutos de formato oblongo e coloracao amarelo-escura e verde-escura, respectivamente. As variedades gardneri e pubescens destacam-se como de maior potencial para a selecao baseada em caracteres de taman |
