In the Krasnodar Territory, dry wind in summer is one of the negative factors of the climate. Rice plants increase transpiration for cooling and gradually lose their turgor due to strong evaporation caused by low relative humidity and strong winds. In the nursery of the competitive test trials, in 2018-2019, we studied different types of rice: ‘Yug2’ with ordinary but folding leaves; ‘Yug-3’ with vertical folding leaves; ‘Yug-5’ and ‘Rubikon’ with vertical non-folding leaves; standard – variety ‘Rapan’ with ordinary leaves. Under conditions of drought and increased plant density, sample ‘Yug-2’ was the best in quantitative terms.
