In a sample of 8300 events of the type ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}n$ and 6800 events of the type ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}p$ obtained with 2.3-BeV/c incident ${\ensuremath{\pi}}^{\ensuremath{-}}$, substantial backward ${\ensuremath{\rho}}^{0}$ production is seen. The decay angular distribution of these backward ${\ensuremath{\rho}}^{0}$ events was found to be anisotropic. The $u$ distribution for the backward ${\ensuremath{\rho}}^{0}'\mathrm{s}$ is compared with the theoretical predictions of the strong-cut Reggeized absorption model. A small amount of backward ${\ensuremath{\rho}}^{\ensuremath{-}}$ production is also seen.
