Abstract

This article presents the results of studying the drought resistance of CMS sorghum lines used as a starting material in the breeding of F1 hybrids. One of the indicators of drought resistance is the determination of the parameters of the water regime of the leaves. The current article examines the indicators of hydration of leaf tissues, their loss of moisture during wilting at the following time intervals: 1.0; 1.5 and 24 hours. Plants of sterile lines were grown from 2019 to 2020 at the experimental grounds of Russian Research and Design-Technological Institute of Sorghum and Corn "Rossorgo". The analysis identifies drought-resistant CMS lines characterized by high total water content (70.32-75.62%) and the least loss of water by leaves 24 hours after wilting (45.25-69.57%). Indicators of stress resistance of plants varied depending on the genotypic features of CMS lines and weather conditions.
