AGS 4 is a hybrid of maize (Zea mays L.) of early-maturing type with FAO 180, intended for cultivation in various climatic zones. The plant is tall, with medium-length ears and a weakly conical shape, weighing from 110 to 140 grams. The grain is intermediate type, closer to dent, with 1000-grain weight ranging from 270 to 300 grams. Leaves are of medium width, slightly curved, and anthocyanic pigmentation of the sheath of the first leaf and roots at the stem is weak or absent. Flowering time of the tassel varies from early to medium, which ensures the hybrid's adaptability to different growing conditions. AGS 4 is distinguished by high resistance to major maize diseases, including southern leaf blight and bacterial blight, as well as very weak infection by common smut. However, the hybrid is susceptible to ear rot caused by Fusarium. Additionally, the variety shows moderate resistance to damage by the grass moth and bollworm, and it is resistant to lodging, which contributes to stable yields and ease of agronomic practices. The hybrid is versatile in use: suitable for grain, feed, silage, and technical purposes. The yield of dry matter in cultivation regions averages 72.6 centners per hectare, while the grain yield, according to the applicant's data, ranges from 45 to 55 centners per hectare. The grain is white, flint-type, making it suitable for production of grits, cereals, and corn sticks. Certified seed material has undergone testing and is adapted to various climatic conditions, ensuring high productivity and resistance of the hybrid.
