  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% for vector mesons,
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 also
discuss reasons for the failure of group theory to produce correct mass
relations for heavy quarkonia.
