In the report, we present the calculation results of some classical effects of GRT of Einstein in the Sun system as the perihelion shift of a planet in its orbit, the deflection angle of light ray near the Sun disk for some f(R) modified gravity models as Starobinsky’s model, Linder’s model and f(R) modified gravity model of polynomial exponential form. The calculation results show that these modified gravity models give very small contributions to GRT's classical effects in the solar system and all are consistent with astronomical observations.
