KSS 7400 — this is a medium-early simple hybrid of corn (Zea mays L.) intended for grain production. The hybrid is characterized by a vegetation period ranging from 98 to 121 days depending on the region, enabling successful cultivation in various climatic conditions, including the Lower Volga, Central Chernozem, and North Caucasus regions. Plants are tall with broad leaves; the anthocyanic coloration of the first leaf sheath is weak, and the leaf tip shape varies from rounded to acute-rounded. Leaves are slightly curved, with a medium angle between the leaf blade and stem, which facilitates good photosynthesis and plant development. The ear is cylindrical, medium in length and thickness, with a short peduncle and medium number of rows of kernels. Kernel type is predominantly dent with intermediate traits; the upper part of the kernel is yellow-orange, while the lower part is yellow. The 1000-kernel weight is 300–320 grams. Ear density is medium, ear shape is slightly conical. Anthocyanic coloration of the ear silk and stalk varies from very weak to medium, which is a distinctive feature of this hybrid. KSS 7400 demonstrates high yield: average yield across regions ranges from 41.3 to 81.9 c/ha, with maximum yields reaching up to 137.1 c/ha. Grain moisture at harvest is within 21.6–27.5%, facilitating storage and processing. The hybrid exhibits good adaptability to various soil-climatic conditions, making it attractive for farmers aiming to achieve high and stable yields of quality grain.
