The usual quark diagram is regarded as the lowest order Feynman diagram describing hadron dynamics. In the lowest order amplitude a factor V is introduced to obtain a dual one. Then the quark mass and the upper bound of the meson trajectory intercept cam be predicted. Funther the physical meaning of V is studied. Firstly, the role of V in the amplitude is analytically investigated. Secondly, one seeks a possibility that V may effectively represent an interaction between quarks. Assuming some Feynman diagrams which may represent a part of the role of V, a Regge trajectory is derived by the penturbative calculation. The trajectory is expanded about t = 0 and it is compared with the trajectory of the dual amplitude. Then the intercept of the leading ordinarytrajectory satisfies alpha (O) = 1/2. (auth)
