We report a measurement of the production ratio of charged and neutral B mesons from Y(4S) decays based on the ratio of efficiency-corrected yields for the charmonium modes J/psiK(+) and J/psiK(s)(0) with 81.9 fb(-1) of data collected with the BABAR detector on the Y(4S) resonance at 10.580 GeV. We find a value of 1.006+/-0.036(stat)+/-0.031(syst) for the ratio R+/0=Gamma(Y(4S)-->B+B-)/Gamma(Y(4S)-->B-0(B) over bar (0)).
