Abstract
Changing climatic conditions and the loss of immunity to diseases and pests of the developed varieties make breeding work to create new genotypes of great necessity. The new middle-early maize hybrid ‘Zernogradsky 299 MB’ of universal direction of economic use (for grain and green fodder) has been developed in the “Agricultural Research Center “Donskoy”. The hybrid is three-linear; it belongs to the varieties with crown yellow grain Zea mays L. indentata. It possesses high values of the main economically valuable traits. The average grain productivity through 3 years of competitive variety testing (2014–2016) was 5.36 t/ha, the variety yield exceeded the standard variety ‘Zernogradsky 291 AMB’ on 0.41 t/ha (8.3%). The average productivity of green mass is 27.6 t / ha, which is higher than that of the standard variety on 2.4 t/ha (9.5%). The new hybrid is resistant to lodging (2.1% of lodged plants), drought-resistant, resistant to smut on a natural background (0.4% of affected plants), has a high starch percentage (71.9%). In 2018, according to the results of the State Variety Testing, a new hybrid was introduced into the State List and approved for use in the Central Blackearth and NizheVolzhsky regions to cultivate it for grain and green fodder. It has a high potential for grain productivity. The maximum yield (11.23 t/ha) was obtained in the Central Blackearth region on the Oboyansk plot of the Kursk region, which is higher than the standard variety ‘Voronezhsky 279 CB’ on 2.03 t/ha (22.1%) with lower grain harvesting moisture (on 1,6%) than the standard variety.

Summary
ФГБНУ «Аграрный научный центр «Донской», Изменение климатических условий и утрата иммунитета к болезням и вредителям созданных сортов обусловливает необходимость селекционной работы по созданию новых генотипов, отвечающих современным требованиям. В «Аграрном научном центре «Донской» создан новый среднеранний гибрид кукурузы Зерноградский 299 МВ универсального направления хозяйственного использования (на зерно и зеленый корм). Средняя урожайность зерна за три года конкурсного сортоиспытания (2014–2016 гг.) составила [5,36] т/га, превышение над стандартом Зерноградский 291 АМВ составило 0,41 т/га (8,3%). По результатам Государственного сортоиспытания новый гибрид внесен в Госреестр и допущен к использованию в производстве Центрально-Черноземного и Нижневолжского регионов для возделывания на зерно и зеленый корм.
