We have measured resistivity, magnetization and magnetoresistance in polycrystalline La0.7-xPrxSr0.3MnO3 with fixed carrier concentration. With decreasing the average ionic radius of the La site (rA), we found a decrease in Tc, an increase in resistivity at Tc, and an increase in the magnitude of the magnetoresistance. The samples show a metal-insulator transition in the high-temperature paramagnetic phase with the variation of (rA). These results demonstrate the close relationship between (rA) and the band structure.
