The measurement of the cross-section of the process π⁺ π⁻ π⁰ with the CMD-3 detector at the electron-positron collider VEPP-2000 in the energy region below 1 GeV in c.m.s. based on a part of the collected statistics with an integrated luminosity of about 16.35 pb⁻¹ is presented. The measured cross-section has been analyzed in the framework of the vector meson dominance model taking into account the interference of ρ, ω, φ, ω', ω'' resonances

Key words: vector meson, collider, detector, hadron interaction
