The 'Sigma' soft spring wheat variety is mid-season and medium-height, with a vegetative period ranging from 79 to 95 days. It is characterized by large grain size and a high 1000-grain weight, varying from 38 to 47 grams. The variety belongs to the 'lutescens' type and exhibits high resistance to lodging, ensuring stable yields. Average yield in the Western Siberia region reaches 24.2 centners per hectare, confirming its good adaptation to growing conditions, particularly in the lowland forest-steppe of Omsk Oblast. Sigma possesses excellent baking qualities, making it in demand for producing high-quality flour. The grain is characterized by high protein and gluten content, as well as flour strength, which positively affects technological properties during baking. The variety outperforms standard samples in purity and grain weight indicators, testifying to its high quality and stability of characteristics. One of the key features of the variety is its high resistance to leaf and stem diseases, such as powdery mildew, leaf rust, and stem rust. This is achieved through the use of a homozygous digenomic line developed by Omsk breeders in collaboration with scientists from the Institute of Cytology and Genetics SB RAS. Such a genetic basis ensures reliable protection of plants from pathogens and contributes to maintaining crop health, which is especially important for increasing yield and grain quality.
