Abstract: More than 20% of agricultural land around the world is suffering from salt stress which hampers plant growth and development. Jute is one of the most important fiber crops that stands second after cotton in the world. Since cultivable land in Bangladesh is decreasing day by day, jute cultivation needs to be moved to the coastal area. Therefore, the aim of our study was to investigate the response of five jute genotypes at different levels of salinity. Germination and seedling growth were focused on as the most critical stages of plant development. In this research, germination percentage (GP), germination index (GI), mean germination time (MGT), seedling vigor index (SVI), shoot & root lengths and fresh & dry seedling weight, and salinity tolerance indices were studied for two-way ANOVA and hierarchical agglomerative classification. Results showed that increasing salinity reduced GP, GI and SVI of the jute genotypes while MGT increased. Having no salt tolerant tossa jute genotype, salt tolerant white jute genotype BJRI Deshi pat 10 was grown simultaneously with four tossa jute genotypes to compare the growth parameters where results indicated that although not as tolerant as BJRI Deshi pat 10, tossa jute genotypes O-043-7-9 G and O-0512-6-2 G showed less salt sensitivity than the other two genotypes O-043-7-9 R and Acc. 4582 G.
