Corn hybrid 'Severina' is an early-maturing three-line hybrid with a vegetative period of about 69 days and belongs to FAO group 140. This hybrid was developed by Kazakh and Russian breeders and is recommended for grain and silage production in various regions of Russia. Plants reach a height of 195 to 240 cm, with ears attached at a height of 80–90 cm. The hybrid is characterized by high yield: maximum grain yields reached over 12 tons per hectare, significantly exceeding standards, and the yield of normalized dry matter was also higher than similar hybrids. The corn 'Severina' grain is dent-shaped, with yellow-orange coloring, where the upper part of the kernel is yellow, and the lower part is yellow-orange. The ears have a cylindrical shape of medium length and diameter, with an average number of rows of kernels. Plants are resistant to lodging and to infection by dusty and bubble smut and ear diseases, ensuring stable yields under various climatic conditions. A distinctive feature of the hybrid is its ability to utilize spring moisture for ear maturation in dry areas, allowing harvest before the onset of hot and dry periods. Additionally, 'Severina' withstands high planting densities up to 80–85 thousand plants per hectare and can produce a second grain harvest in southern regions under irrigation. These qualities make the hybrid versatile and economically advantageous for cultivation in diverse agroclimatic zones.
