The major role that soybeans may have in perspective is also related to the plant's attribution to fix the nitrogen in the atmosphere and to use it with high yield in the process of assimilation.To study the link between the quality characteristics considered in the three soybean varieties it was used the calculation of the correlation coefficients (r). The study of the existing links between the analysed characters is of great utility in the production by allowing the selection that simultaneously holds the combination of useful characters, but at the same time draws attention to the difficulty of achieving these requirements.
