Inclusive production of the f0(980), f2(1270) and φ(1020) resonances has been studied in a sample of 4.3 million hadronic Z0 decays from the OPAL experiment at LEP. A coupled channel analysis has been used for the f0 in simultaneous fits to the resonances in inclusive π+π- and K+K- mass spectra. Fragmentation functions are reported for the three states. Total inclusive rates are measured to be 0.141 ± 0.007 ± 0.011 f0, 0.155 ± 0.011 ± 0.018 f2 and 0.091 ± 0.002 ± 0.003 φ mesons per hadronic Z0 decay. The production properties of the f0, including those in three-jet events, are compared with those of the f2 and φ, and with the Lund string model of hadron production. All measurements are consistent with the hypothesis that the f0(980) is a conventional qq̄ scalar meson.
