SSK 311 — mid-early hybrid maize, intended for grain and silage cultivation. The plant features a robust stem reaching 200 to 270 cm in height and a well-developed root system, ensuring its resilience and adaptability to various growing conditions. The leaves are yellow-green, and the cylindrical ear with a well-developed tip reaches 16–24 cm in length and 4.5–5 cm in diameter. The ear attachment height is 90–100 cm, facilitating convenient harvest.
The grain of this hybrid has a cream-colored, toothed type, orange or yellow in color, with high starch and protein content. The number of rows per ear varies from 16 to 18, with 36–40 kernels per row. The 1000-kernel weight ranges from 310–340 g, indicating high grain density and quality. A thin red ear stalk is a distinctive feature of this hybrid.
SSK 311 is distinguished by high heat and drought resistance, making it competitive under variable climatic conditions. The hybrid is adapted to various agronomic conditions, ensuring stable yields of 11.3–14.0 t/ha at 14% grain moisture. Optimal sowing and harvest timing allow for maximum utilization of the plant's potential to produce high-quality grain and silage.
