Исследования проведены в лесостепной зоне Воронежской области в 2022, 2023 гг. Объектами опытов послужили родительские формы раннеспелых гибридов кукурузы Воронежский 130 МВ, Воронежский 135 СВ, Воронежский 145 МВ, Воронежский 150 СВ, Воронежский 171 СВ, Воронежский 182 МВ. Агротехнические мероприятия соответствовали общепринятым нормам для зоны. Результаты дисперсионного анализа показали, что условия года, генотип, схема размещения и густота стояния оказывали влияние на урожайность материнских компонентов (p = 0,001). Уборочная влажность зерна определялась теми же факторами опыта, однако условия года формировали значения показателя только для группы второго срока посева (p = 0,001), а достоверного действия схемы размещения не выявлено. Загущение посевов до 70 тыс./га способствовало увеличению показателей урожайности (0,36–0,75 т/га) и уборочной влажности (0,3–1,2%) зерна в сравнении с густотой стояния 50 тыс./га. Схема размещения 6 : 2 повышала продуктивность (0,44–0,66 т/га) материнских компонентов в отличие от схемы 4 : 2. Совокупное действие установленных в ходе исследований показателей определено как оптимальное для изученных родительских форм гибридов и рекомендовано к использованию в производственном семеноводстве. </p></abstract><trans-abstract xml:lang="en"><p>The results of the tests of parental lines of corn hybrids to determine the optimal schemes of placement and plant density are presented. The research was conducted in the forest-steppe zone of the Voronezh region in 2022–2023. The parental lines of the early maturing corn hybrids Voronezhsky 130 MV, Voronezhsky 135 SV, Voronezhsky 145 MV, Voronezhsky 150 SV, Voronezhsky 171 SV, Voronezhsky 182 MV served as the objects of experiments. Agronomic measures were in line with generally accepted norms for the zone. The results of analysis of variance showed that year conditions, genotype, placement pattern and stand density influenced the yield of the female parent components (p = 0.001). Grain moisture at harvest was determined by the same experimental factors, with environmental conditions affecting the values only for the second sowing date group (p = 0.001), while no significant effect of ratios was observed. Thickening of crops to 70,000 plants/ha led to an increase in the yield (0.36–0.75 t/ha) and grain moisture at harvest (0.3–1.2%) compared to the plant density of 50,000 plants/ha. The placement pattern 6 : 2 increased female parent components performance (0.44–0.66 t/ha) unlike the scheme 4 : 2. The combined effect of the parameters identified during the study was determined to be optimal for the parental components of the hybrids and recommended for use in commercial seed production.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кукуруза</kwd><kwd>родительские формы</kwd><kwd>схема посева</kwd><kwd>густота стояния</kwd><kwd>продуктивность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>corn</kwd><kwd>parental lines</kwd><kwd>sowing pattern</kwd><kwd>stand density</kwd><kwd>productivity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Jiao Y., Chen H.D., Han H., Chang Y.
