We measure the ratio of branching fractions R-1 = B(J / psi -> K+K-pi(0))/B(J / psi ->pi(+)pi(-)pi(0)) and R-2 = B(J / psi -> K-S(0) K-+/- p(-/+))/B(J / psi ->pi(+)pi(-)pi(0)). We perform Dalitz plot analyses of the three J / psi decay modes and measure fractions for resonances contributing to the decays. We also analyze the J /psi -> pi(+)pi(-)pi(0) decay using the Veneziano model. We observe structures compatible with the presence of rho(1450) in all three J / psi decay modes and measure the relative branching fraction: R(rho(1450)) = B(rho(1450)-> K+K-)/B(rho(1450)->pi(+)pi(-)) = 0.307 +/- 0.084(stat) +/- 0.082(sys). %R 10.1103/PhysRevD.95.072007 %U http://arxiv.org/abs/1702.01551 %U https://doi.org/10.1103/PhysRevD.95.072007 %P 072007-19pp
