Maize Rosomak

Rosomak — a medium-early corn hybrid (Zea mays L.), included in the State Register for the Central Chernozem and Lower Volga regions for grain production. Medium-height plant with medium-sized leaves and slightly curved leaf blades. Tassel flowering occurs in early-to-medium terms. Medium-length, weakly conical ear with a large number of rows of orange-colored kernels. Kernel type is intermediate, closer to flint. The hybrid exhibits moderate resistance to common rust and weak anthocyanin pigmentation of some plant parts. The Rosomak hybrid is characterized by good stem strength and resistance to Fusarium wilt, enhancing its reliability under various agroclimatic conditions. It is adapted for cultivation on lighter soils and areas with insufficient rainfall, making it a promising choice for regions with variable moisture levels. In 2012, the variety successfully passed trials in Romania and Ukraine, demonstrating high yields even under water deficit. Average grain yield in the Central Chernozem region reaches 82.8 c/ha, which is 14.5% higher than the standard, and in the Lower Volga region — 52.6 c/ha, which is 4.4% higher than the standard. The vegetative period ranges from 101–116 days depending on the region. Pre-harvest grain moisture is at an optimal level, facilitating harvesting and storage. Choosing the Rosomak hybrid, farmers obtain a reliable and high-yielding material suitable for various cultivation zones.
