The investigation in the work of the reaction e{sup +}e{sup -}{yields}{omega}{pi}{sup 0} in the {sup 3}P{sub 0} nonrelativistic quark model reveals that the e{sup +}e{sup -}{yields}{omega}{pi}{sup 0} process at the energy region from the {omega}{pi} threshold to 2.0 GeV is dominated by the two-step process in which the primary qq pair first forms {rho} and {rho}{sup '} mesons and then the vector mesons decay into {omega} and {pi}. With {rho}(1450) and {rho}(1700) mainly in 2S and 1D states, respectively, the experimental data for the cross section of the reaction e{sup +}e{sup -}{yields}{omega}{pi}{sup 0} are well produced in the {sup 3}P{sub 0} quark model. The work supports the argument that {rho}(1450) is mainly a 2S meson and {rho}(1700) a 1D meson.
