OMSK 101 is a medium-early spring barley (Hordeum vulgare L.) variety intended for grain and fodder use. The variety's vegetation period ranges from 70 to 101 days, allowing for efficient cultivation in the West Siberian region, including the Altai Krai and Omsk Oblast. The plant is medium-height with an erect or semi-erect culm, resistant to lodging, which facilitates harvesting and improves crop quality. The ear is pyramidal, loose, with a waxy bloom of medium intensity, and the grain is large with a characteristic glabrous ventral groove and embracing lodicules. The 1000-grain mass varies from 44 to 56 grams, indicating good potential for yield and grain quality. The average yield of the variety in the West Siberian region is 37.2 centners per hectare, with maximum figures reaching up to 59.3 centners per hectare. Protein content in the grain reaches 15.1%, making the variety attractive for fodder use. OMSK 101 has moderate resistance to loose smut and damage from the cereal leaf beetle, but is highly susceptible to helminthosporiosis and root rots, requiring careful attention to plant protection during the vegetation period. The variety was developed at the Omsk Agrarian Scientific Center and passed state trials confirming its adaptation to the climatic conditions of Western Siberia. Compared to other spring barley varieties, such as Omsk 95 and Omsk 102, OMSK 101 demonstrates competitive indicators for protein content and grain mass. Its characteristics make it in demand for agricultural production, ensuring a stable and high-quality yield in growing regions.
