We have studied the production of B hadrons in 1.8-TeV pp collisions. We present measurements of the fragmentation fractions, fu, fd, fs, and fbaryon, of produced b quarks that yield B+, B0, B0s, and B¯0b hadrons. Reconstruction of five electron-charm final states yields fs (fu + fd) = 0.213 ± 0.068 and fbaryon/ (fu + fd) = 0.118 ± 0.042, assuming fu =fd. If all B hadrons produced in pp¯ collisions cascade to one of these four hadrons, we determine fu = fd = 0.375 ± 0.023, fs = 0.160 ± 0.044, and fbaryon = 0.090 ± 0.029. If we do not assume fu = fd, we find fd/fu = 0.84 ± 0.16.
