Electron transport and magnetic properties of several compositions of the La1-xSx-zYzMnO3 system have been investigated in order to explore the effect of yttrium substitution on the magnetoresistance and related properties of these manganates. Yttrium substitution lowers the T-c and the insulator-metal transition temperature, while increasing the peak resistivity. A comparison of the properties of La1-xSrx-zYzMnO3 with the corresponding La1-xCax-zYzMnO3 compositions shows that the observed properties can be related to the average size of the A-site cations.
