Corn hybrid KSS 5284 is a medium-early simple hybrid intended for grain production under various climatic conditions. The vegetation period ranges from 98 to 116 days depending on the region, enabling the hybrid to successfully adapt to different agroclimatic zones. Plants are tall with straight or slightly curved leaves of medium width and rounded apex of the first leaf. The ear is long and weakly conical in shape, with medium-row density of kernels having an intermediate type, closer to flint or dent. Kernel color varies from yellow-orange to orange, indicating high quality and product attractiveness. Hybrid KSS 5284 is characterized by high yield and stable performance. Average yields across various regions range from 41.3 to 83.1 centners per hectare, with maximum values reaching 143 centners per hectare. Grain moisture at harvest is approximately 22%, meeting standards and facilitating storage and processing. The plant exhibits weak or moderate anthocyanin pigmentation in various parts, including the sheath of the first leaf, roots, and silk, which is an important trait for selection and identification of the hybrid. A distinctive feature of corn KSS 5284 is its high resistance to common diseases such as rust, stem and root rot, as well as good drought tolerance and resistance to other adverse environmental factors. This makes the hybrid a reliable choice for farmers seeking a stable and high-quality harvest. High germination capacity and seed purity ensure excellent results in cultivation, confirmed by successful application of the hybrid in various regions.
