We report results of searches for charmless hadronic B meson decays to pseudoscalar(pi+-,K+-,Pi⁰ or Ks⁰)-vector(Rho, K* or Omega) final states. Using 9.7 million BBbar pairs collected with the CLEO detector, we report first observation of B- --> Pi-Rho⁰, B⁰ --> Pi+-Rho-+ and B- --> Pi-Omega, which are expected to be dominated by hadronic b --> u transitions. The measured branching fractions are (10.4+3.3-3.4+-2.1)x10-6, (27.6+8.4-7.4+-4.2)x10-6 and (11.3+3.3-2.9+-1.4)x10-6, respectively. Branching fraction upper limits are set for all the other decay modes investigated.
