          Abstract

          Este estudo objetivou estimar os parâmetros genéticos relativos à qualidade do sistema radicular de mudas de baru. Para isso, foram utilizadas mudas provenientes de sementes colhidas em 21 árvores-matriz de polinização livre no Município de Capinópolis, Minas Gerais. Quarenta e cinco dias após a germinação, as imagens das raízes de 20 mudas de cada progênie foram obtidas por "scanner" ótico. Na análise de variância, houve variação significativa entre as progênies quanto aos caracteres: comprimento total de raízes, volume de raízes, diâmetro médio e número de raízes finas. As análises indicaram altos valores de herdabilidade e coeficiente de variação genética, indicando que altos ganhos genéticos poderão ser obtidos mediante a seleção de matrizes.

          Translated abstract

          Baru seedlings originated from seeds collected from 21 open-pollinated progenies were used in Capinópolis, Minas Gerais, Brazil, in order to estimate genetic parameters concerning the quality of their root system. Forty-five days after germination, the root images of twenty seedlings of each progeny were obtained using an optical scanner. The analysis of variance showed significant variation among progenies in total root length, root volume, average diameter and the number of fine roots. The analysis showed high heritability and genetic variation, indicating that high genetics gains are possible to be obtained by means of mother-tree selections.
