Abstract
In modern times, the development of each country is measured primarily by ensuring food security. To obtain a high yield from agricultural plants, varieties that are suitable for the soil and climatic conditions of each zone should be selected and studied, and breeding work should be carried out on them to obtain more suitable and productive varieties for local conditions. The main goal of our research is the creation and breeding of winter wheat varieties with high productivity and stable genetic traits, resistant to diseases, pests and various climatic conditions. Breeding for resistance to diseases of winter bread wheat is one of the most important and complex, and in our regions the most important area of breeding.
