Temperature dependence of resitivity, ρ(T), thermopower, S_{300}, superconducting transition temperature, T_{c}, and lower critical field, Η_{c1}(0), of differently doped REBa_{2}Cu_{3}O_{7-x} ceramics have been measured. The hole doping of the CuO_{2} plane is determined by the T_{c}, the oxygen concentration and/or the value of the thermopower. The temperature dependence of the resistivity above 200 K and the values of the lower critical field H_{c1}(0) show clear dependence on the hole concentration. Below 200 K, in contrast to simple metals, the resitivity of all samples decreases faster than linearly with the decreasing temperature. Classical electron-phonon scattering mechanism is not appropriate to describe the ρ(T) curves of REBa_{2}Cu_{3}O_{7-x} compounds. Some observed features of the ρ(T) dependence are predicted by mean field phase diagram for the CuO_{2} plane.
