We have analyzed the spectrum of hadrons by the latest data available through theParticle Data Group, with the aim of pinpointing trajectories with which hadronic resonancescan be associated. It was recognized that the entire range of Regge trajectories (RTs) forhadrons are not straight and parallel lines. Out of total 66 plotted trajectories, 64.81% areessentially non-linear, 27.78% are essentially linear, while 7.41% are fairly linear. We haveextracted a number of inherent parameters of these RTs such as slopes, variance, string tensionamong quarks and have deduced results which are both in coherence as well as in sharp contrastto the conventional ones. Existence of 15 new resonance particles has been predicted along withsome of their intrinsic parameters. The flavour dependence of RTs is also interrogated.
