We present evidence for leading particle production in hadronic decays of theZ0 boson to light-flavor jets. A polarized electron beam was used to tag quarkand antiquark jets, and a vertex detector was employed to reject heavy-flavorevents. Charged hadrons were identified with a Cherenkov ring imaging detector.In the quark jets, more high-momentum p, Lambda, K-, and anti-K*0 were observedthan their antiparticles, and vice versa for antiquark jets, providing directevidence that the higher-momentum particles in jets are more likely to carrythe primary quark or antiquark from the Z0 decay, and that s-s(bar) productionis suppressed in fragmentation.Comment: 8 pages LaTeX and 2 encapsulated postscript figures, submitted to Physical Review Letter
