We calculate the F/D ratios of spin 1/2 baryon vertex for both the non-relativistic quark model and the chiral soliton model with arbitrary number of color degrees of freedom N_c and examine the results in terms of the consistency condition approach for the baryon vertices recently developed by Dashen, Jenkins and Manohar from the viewpoint of QCD. We show that the l/N_c corrections have two different origins, i.e., one is from the baryon states or baryon wave functions and the other from the vertex operators. Although in the limit N_c→∞ the F/D tends to 1/3 in all models, the l/N_c expansion of F/D ratio does not converge for N_c=3 in the chiral soliton model in contrast to the non-relativistic quark model.
