The basis of the creation of self-pollinated lines is the inbreeding method, which ensures homozygosity and individual selective selection and allows choosing the best samples for further reproduction. Based on the results of research, 14 best self-pollinated lines were selected, of which 8 are mid-early and 6 are mid-ripening. In the conditions of the Forest Steppe of Ukraine, the selection of self-pollinated corn lines is effective based on the characteristics of ꞌꞌduration of the period ꞌꞌseedling-flowering of 50% of the cobsꞌꞌ, ꞌꞌplant heightꞌꞌ and ꞌꞌcob attachment heightꞌꞌ, and component elements of productivity ("cob weight and length", "number of rows of grains", "number of grains in a row"). At the same time, it is necessary to take into account that for the maximum realization of the genetic potential of the plant, the selection should be carried out comprehensively, taking into account all these indicators at the same time. In the reporting year, the volume of testing of new hybrids in the competitive nursery amounted to 38 samples - 21 mid-early and 18 mid-ripe. The yield level in 2025 varied from 6.4 t/ha to 9.4 t/ha, while the harvesting moisture was from 15.2 to 32.8%. According to the results of the test, the best hybrids were selected (5 in the mid-early group, 7 in the mid-ripe group), which significantly exceeded the values ​​of the standards and had high resistance to root rot (100%). According to the results of research, three self-pollinated lines - Uk 33 (FAO 230), Uk 6619 (FAO 230) and Uk 63 (FAO 250) and two mid-early corn hybrids - Ukrainian Gold and Spadok, which are characterized by resistance to major diseases and pests and are adapted to the conditions of the Forest Steppe of Ukraine, were transferred to the State Register of Plant Varieties.
