By assuming the existence of (quasi)-linear Regge trajectories for 25-plet mesons in the low energy region, we derive a new, 14th power, meson mass relation. This relation may be reduced to a quadratic Gell-Mann-Okubo type formula by fitting the values of the Regge slopes of these (quasi)-linear trajectories. Such a formula holds with an accuracy of 2 and also suggests that the quantum number I(J^P)=1/2(2^+) should be assigned to the both B_J(5732) and B_sJ(5850) mesons discovered recently. We
