RUBENIUS — this is a mid-early three-line hybrid of corn (Zea mays L.), primarily intended for silage production. It is characterized by high yield of normalized dry matter, reaching 153.3 centners per hectare in the Central Chernozem region with dry matter content around 44.5%. The hybrid shows low susceptibility to diseases such as ear rot, fusarium, and powdery mildew, as well as moderate resistance to pests, particularly the stalk borer. RUBENIUS plants exhibit high resistance to lodging and moderate flowering time, ensuring stable yield formation. The growing period of the hybrid is approximately 110 days, and plant height ranges from tall to very tall, promoting good development and ear formation. The hybrid is suitable for various cultivation technologies, including conventional and minimum tillage, as well as irrigation, making it a versatile choice for different agroclimatic conditions. RUBENIUS is recommended for cultivation in the Central Chernozem, North Caucasus, and Lower Volga regions, where it demonstrates high productivity and resistance to adverse factors. Due to its characteristics, this hybrid is a reliable solution for farmers aiming to obtain high-quality silage and grain with good yield and resistance to diseases and pests.
