We use data collected with the CLEO II detector to perform a high-statistics measurement of the resonant substructure in D0K-π+π0 decays. We find that the Dalitz plot is well represented by a combination of seven quasi-two-body decay channels [K*0π0,K-ρ,K*-π+,K0(1430)-π+,K0(1430)0π0,K-ρ+(1700), and K*(1680)-π+], plus a small non-resonant component. We see no evidence of a scalar κK-π+ resonance in the mass range recently reported by other groups. Using the amplitudes and phases from this analysis, we calculate an integrated CP asymmetry of -0.031±0.086.
