Soft spring wheat of the Polyusko variety is a medium-maturing variety developed at the Federal Research Center Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences. The variety's pedigree includes the Obskaya 14 and Novosibirskaya 22 lines. The vegetative period ranges from 69 to 96 days depending on the region and growing conditions. The variety is characterized by a cylindrical spike and a 1000-grain weight of 29.4 to 40 grams, indicating high grain density and quality. Polyusko belongs to strong wheats with excellent baking qualities; protein content reaches 14.1%, and gluten content is 32%. The variety is distinguished by high resistance to lodging and drought, especially during the initial growth phases, and a well-developed root system, which contributes to its adaptation to various soil and climatic conditions. Despite moderate resistance to lodging and drought, the variety is susceptible to certain diseases, such as common bunt, septoria, powdery mildew, brown rust, and root rots, which require timely application of protective measures. Polyusko is recommended for cultivation in the West Siberian region, including the Altai Krai and the steppe zone of the Omsk region, and is also suitable for reseeding damaged winter crops. The average yield of the variety in the region is about 18.7 centners per hectare; moreover, the variety responds positively to fertilizer application, which allows increasing productivity and grain quality. Thanks to its biological features and adaptive properties, Polyusko wheat is a reliable choice for agricultural producers seeking to obtain a stable and high-quality crop of soft spring wheat.
