 The purpose of the work is to improve the theoretical basis for the creation of intensive maize hybrids for irrigation conditions. Create 4 hybrids of corn of different maturity groups with high adaptability to irrigation conditions, low grain harvest moisture and yield of 14.0–16.0 t / ha. Research methods - experiments were conducted in the field of field experiments. Methods of hybridization, inbreeding, artificial selections with the study of combinatorial ability were used. Resistance to disease was studied. The mobilization of new source material was carried out, selections, testing of families and lines were carried out. Crossing of perspective parental forms is carried out, among them parental components on high productive and adaptive potential, the best combination ability for the further involvement in crossing are revealed. Promising test-cross combinations and inbred morphobiotypes among the best families and hybrids for various selections in the control and competitive variety testing have been identified. A new source material has been created. The bases of creation of hybrids of intensive type corn for irrigation conditions are theoretically substantiated and 4 adaptive hybrids of intensive type for irrigation conditions are created.
