MIAR is a mid-early spring barley (Hordeum vulgare L.) variety intended for grain and fodder use. It is characterized by moderate plant height and a vegetative period of 74 to 94 days. The mass of 1000 grains varies within 43-57 grams, indicating good grain quality. The variety is resistant to lodging, which facilitates harvesting and reduces crop losses. Protein content in the grain ranges from 11.1% to 15.0%, ensuring its nutritional value for fodder purposes. MIAR is recommended for cultivation in various regions of Russia, including the Central, Volga-Vyatsky, Central-Black Earth, and Middle Volga regions, as well as in Bryansk, Ivanovo, Moscow, Ryazan, Sverdlovsk, and Oryol regions, as well as in the Mari El, Udmurtia, and Tatarstan republics. The variety yields an average of 20.7 centners per hectare, making it attractive to agricultural producers. The variety shows moderate susceptibility to loose smut and susceptibility to dwarf rust and helminthosporiosis, however, in field conditions, infection by helminthosporiosis and loose smut was insignificant. MIAR is a reliable choice for farmers seeking a stable and high-quality barley harvest. Due to its resistance to lodging and good agronomic characteristics, the variety is suitable for cultivation in diverse climatic conditions. It provides high grain quality, which is important for fodder use, and promotes efficient farming in recommended regions.
