The aim of the study was to evaluate salt resistance of corn lines and hybrids at early stages of plant growth and development, as well as at the level of haploid male gametophyte. Under stress conditions of chloride salinity, the variability of such traits as "seed germination", "seedling length", "rootlet length", "number of rootlets" was studied. Correlations and regressions of traits, effects of the factors "genotype", "salinity stress", as well as their interaction were assessed. As a result, reliable positive correlations of the studied traits of early growth and development under salt stress were established, and reliable effects of the "genotype" factor in the variability of traits at the diploid and haploid levels were determined. The hybrid combination with the maternal component L276xP165, as well as the lines P343, L1866, Mo17, Co125 turned out to be genotypes with increased salt resistance.
