Rice resistance to soil and water salinity plays an important role in agriculture, as it affects the productivity of plants in areas with high salt content. This article provides information on the identification of samples with the Saltol tolerance gene from hybrid rice populations obtained from hybridization of the Russian variety Novator with Asian donors of this gene. In laboratory analysis of salt resistance, rice seeds were germinated in glasses with a 1.5% solution of table salt and distilled water. The ratio of the mass of young 10-day plants in the experiment to the control was used as an indicator of stability. In the course of the work, samples tolerant to salinization were selected. PCR analysis showed that most of them contained the gene Saltol in their genotype. The best lines were tested for productivity in the field on plots of 25 m2 in 2-fold repetition. The elements of the crop structure are also studied. Two samples 7328/17 and 7322/17 from a combination of IR-52713-2B-8-2B-1-2 x Novator in an average of two years showed a yield of 6.82-7.53 t/ha, while the variety-standard Uzhanin 6.25 t/ha). The increase was 0.57-1.28 t/ha.
