Abstract: The article presents the results of an analysis of physiological indicators of the total content of chlorophyll “a” and chlorophyll “b” on the leaves of plants during mass podding in domestic and foreign soybean varieties grown under different conditions of water availability. Under conditions of water deficiency, in some varieties, there is an increase in chlorophyll “a”, chlorophyll “b” and an increase in the total amount of chlorophyll, and in some varieties, on the contrary, it decreases. This indicates that the content of plastid pigments in the leaves of plants varies depending on the biological characteristics of the varieties and water supply conditions.

Keywords: soybean, variety, water regime, simulated drought, nature, total chlorophyll, chlorophyll “a”, chlorophyll “b”, adaptation.
