This article discusses the main physiological indicators of water exchange in winter wheat varieties Makus-3, Istiklal and Istiklal-20. There were revealed indicators of daily and residual water deficit of leaves, as well as the water potential of leaves.As you are aware, drought resistance of plants depends on a number of factors. In particular, it is largely determined by the biological characteristics of plants.In this regard, the identification of the features of the physiological processes of the water regime and the associated metabolic processes that determine the resistance to drought in various varieties and hybrids of wheat is of great interest not only in scientific but also in practical terms, because the research results can be used to develop recommendations for selection of source forms for breeding work. We have studied a number of indicators of the water regime of local varieties of winter wheat -Istiklal, Istiklal-20 and Makus-3. The research was carried out on plants grown under the conditions of vegetation and field experiments in the phases of booting, earing, flowering and waxy ripeness.
