Salinity is one of the most important abiotic stress factors causing serious problems in agricultural areas in the world. In this study aimed to determine the salt stress tolerance of local bread wheat genotypes collected from some provinces of Turkey and provided from seed gene banks in our country in early growth stage. In the research, twenty five local bread wheat genotypes and four registered bread wheat cultivars as standard were used as material. Genotypes were subjected to salt stress germination percentage, radicle length, coleoptile length, shoot length, germination index, root fresh and dry weight, were measured. Germination percentage was decreased significantly by 39.1 % in salt application compared to the control. According to the germination percentages, TR 53869, Kate A1 and Pehlivan genotypes were found to be tolerant to salt stress in early growth stage TGB 000543 and TR 63579 were sensitive. Considering all traits investigated, genotype TR 53869 can be considered as a genotype tolerant to salt stress in early growth stage. It is predicted that this genotype can be used in breeding studies for the areas where salt stress is a problem in wheat.
