  We report results of a Dalitz plot analysis of the three-body charmless
B0=>K0pi+pi- decay. The analysis is performed with a data sample that contains
388 million BBbar pairs collected near the Y(4S) resonance with the Belle
detector at the KEKB asymmetric energy e+e- collider. Measurements of branching
fractions for the quasi-two-body decays B0=>rho(770)0K0, B0=>f0(980)K0,
B0=>K*(892)+pi-, B0=>K*(1430)+pi-, and upper limits on several other
quasi-two-body decay modes are reported.
