At hadron colliders the dominant production mechanism of ({bar {ital b}}{ital c}) mesons with large transverse momentum is due to parton fragmentation. We compute the rates and transverse momentum spectra for production of {ital S}-wave and {ital P}-wave ({bar {ital b}}{ital c}) mesons at the Fermilab Tevatron via the direct fragmentation of the bottom antiquark as well as the Altarelli-Parisi-induced gluon fragmentation. Since all the radially and orbitally excited ({bar {ital b}}{ital c}) mesons below the {ital BD} flavor threshold will cascade into the pseudoscalar ground state {ital B}{sub {ital c}} through electromagnetic and/or hadronic transitions, they all contribute to the inclusive production of {ital B}{sub {ital c}}. The contributions of the excited {ital S}-wave and {ital P}-wave states to the inclusive production of {ital B}{sub {ital c}} are 58 and 23 {percent}, respectively, and, hence, significant. {copyright} {ital 1996 The American Physical Society.}
