The features of interrelations in the pathosystem Zea mays and Ustilago zeae under artificial infectious background conditions are studied. The photos are presented and the symptoms of corn smut expression on vegetative and reproductive plant organs are described in all the details. The methods of plant inoculation by the fungus U. zeae are described in early, primary stages of the crop ontogenesis and the evaluation of stem and leaves infection by corm smut agent in 7 regionalized corn hybrids is accomplished. The pathogenesis features in local perspective hybrid Polessky 193 SV in the course of plant vegetation are observed. Different infection of vegetative and reproductive organs of the hybrid Polessky 193 SV °У corn smut agent is marked and field resistance is determined
