Abstract: The charged particle multiplicities of the quark and gluon jets in the three-fold symmetric e+e- --> qg events at [radical sign]s = 29 GeV have been studied using the high resolution spectrometer at PEP. A value of n>g = 6.7-2.1+1.1+/-1.0 for gluon jet s with an energy of 9.7-2.0+1.5 GeV is measured. The ratio, n>g/n>q, is 1.29-0.41+0.21+/-0.20, which i s significantly lower than the value of 9/4 naively expected from the ration of the gluon-to-quark color charges.
