The Locally Rotationally Symmetric (LRS) Bianchi type I cosmological model with variable modified Chaplygin gas having the equation of state =−/, where 0≤≤1, is a positive constant, and is a positive function of the average-scale factor () of the universe (i.e., =()) has been studied. It is shown that the equation of state of the variable modified Chaplygin gas interpolates from radiation-dominated era to quintessence-dominated era. The statefinder diagnostic pair (i.e., {,} parameter) is adopted to characterize different phases of the universe
