In this paper, we report on the measurement of the rate of inclusive {pi}{sup 0} production induced by charged-current neutrino interactions in a C{sub 8}H{sub 8} target at a mean energy of 1.3 GeV in the K2K near detector. Out of a sample of 11 606 charged-current neutrino interactions, we select 479 {pi}{sup 0} events with two reconstructed photons. We find that the cross section for the inclusive {pi}{sup 0} production relative to the charged-current quasielastic cross section is ({sigma}{sub CC{pi}{sup 0}}/{sigma}{sub CCQE})=0.426{+-}0.032 (stat){+-}0.035 (syst). The energy-dependent cross section ratio is also measured. The results are consistent with previous experiments for exclusive channels on different targets.
