In this research, 25 species from the gene pool of plant genetic resources of the Rice Research Institute based on the characteristics of the varieties and 9 high-quality yields that can be grown in different and highly saline conditions, regionalized varieties were selected. Obviously, seed germination, seedling thickness and pre-harvest storage performance of those varieties were studied. Further development of rice in different saline conditions, efficient use of natural and other resources, increase of productivity and its quality was researched. In the experiment, in strongly saline soils, in the 4th variant with Cl ion 0.1 - 0.2%, the germination rate was 10.1-34.9% in early ripening varieties of rice, 17.8-25.6% in medium ripening varieties, 11.6-23.0% in late ripening varieties. However, in the 5th variant of the very strongly saline experiment, where the Cl ion content in the soil was higher than 2.0%, the seed germination in early ripening varieties of rice was 0.0-32.9%, 0.0-11.7% and 0-12.3% in middle ripening, and in late ripening varieties, respectively.
