This study presents the findings of research aimed at determining the seed yield and harvesting moisture of inbred lines, parental components of maize hybrids of various FAO groups, depending on sowing dates in the agroecological conditions of the Forest-Steppe region of Ukraine. The research is based on the evaluation of different FAO group lines-parental components of Ukrainian breeding: early-maturing - OR26A (FAO 240), AV20B (FAO 260), OR28A (FAO 260); mid-maturing - OR32A (FAO 320), AV30B (FAO 320). The seed moisture content before harvest for the lines-parental components of hybrids varied within the FAO group and sowing dates. Yield calculation demonstrated that the realization of seed yield potential for each inbred line depends on the genotype and sowing dates. Improving the elements of variety agrotechnics for lines - parental components of maize hybrids of different FAO groups provides an opportunity to increase seed productivity of lines for timely seed provision of hybridization areas and the accelerated introduction of innovative hybrids into production.
