The aim of the study was to study the effect of salt solutions of different concentrations on seed germination in 7 tomato varieties and 3 hybrids in the Republic of Karakalpakstan. The following options were studied in the studies: dry seeds (control 1); - seeds soaked in water (control 2); - seeds dissolved in solutions: 0.3% NaCl; - 0.5% NaCl; - 0.7% NaCl; - 1.0% NaCl; - 0.3% Na2SO4; - 0.5% Na2SO4; - 0.7% Na2SO4; -1.0% Na2SO4. The experiment revealed that tomato varieties and hybrids are resistant to chloride and sulfate salinity at the lowest concentrations (0.3 %). It was proven that a further increase in the concentration of salt solutions (from 0.5 to 1.0 %) negatively affects the quality of sowing seeds. When determined the germination power and seed germination in NaCl solutions, varieties of tomato Rio Grande, Novichok, UzMASh-1, TMK-22 and Solerosso F1 hybrids were the best among the studied samples.
