Item Screening of corn genotypes for salinity resistance [Articol](Editura USM, 2025) Climenco, OxanaThe 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.Item Selection of resistant maize genotypes under salt stress and drought conditions(CEP USM, 2024-10-07) Climenco, OxanaThe variability of the characters "seedling length" and "root length" at the initial stages of plant development depended significantly on the factors "genotype", "abiotic stress" and on the interaction "genotype x stress". The effect of the factor "genotype" was at a high level for the characters "number of branches in the panicle" and "panicle length". The values of the effect of the factor "genotype" for the characters "number of rows per cob" and "number of grains per row" were at an average level. Under osmotic stress conditions only two hybrids with the maternal line L1866 had the relatively high values of the «pollen grain diameter» character. Under saline stress conditions, the effects of both the "stress" factor and the "genotype x stress" interaction were significant. The highest values of the studied character demonstrated hybrids with paternal genotypes lines B73 and W23.
