The aim of this study was to evaluate the correlations between vegetative and productive characteristics of banana tree (Musa spp) cv 'Prata-Anã' (genomic group AAB) differently managed from the conventional system. The experiment was carried out in an orchard with five years old banana plants spaced by 3,5 x 2,0 m, in the Fazendas Reunidas FFL Ltda., at Cristais Paulista, São Paulo, Brazil. The experiment was a split plot under a completely randomized design with three replicates, being the main treatments constituted by: M1 - daughter-plant without the mother-plant whose stem was cut after flowering; M2 - daughter-plant and mother-plant conventionally managed until harvest. The sub plots were constituted by twelve periods of selection of the daughter-plants (February 2002 to January 2003). The pseudostem diameter and the bunch weight of all plants and the vegetative period of the daughter-plants were evaluated. The statistical analysis showed a positive correlation between the stem diameter of the daughter-plants and mother-plants. The stem diameter of the mother-plant was positive correlated with its bunch weight. However the stem diameter of the daughter-plant not was correlated with its bunch weight. The vegetative cycle and the pseudostem diameter of the daughter-plants were negatively correlated. The Plant management (M1 and M2) and the selection of periods daughter-plant did not affected the correlations evaluated in this study.
