Analysis of yield and yield components traits in the advanced yield trial of winter bread wheat

In recent years, a number of scientific and practical work is being carried out in the country to create new varieties of cereals, especially soft wheat. The grain fields of our country are enriched with new varieties of soft wheat created by local and world breeders. The main part of wheat grown in our region is winter soft wheat (ordinary) varieties belonging to the genus T. Aestivum L. In the last decade, grain yield loss due to epithelium of yellow rust disease has increased by more than 30 percent. In addition, weather factors (drought, high temperature, cold, in some years the arrival of excessive rainfall in the spring months) are repeated seasonally. In this regard, the creation of varieties resistant to major pathogens and adaptable to abiotic stresses remains very important and relevant.
