Abstract:
To obtain salt tolerant genotypes, salt tolerance of 10 jute genotypes of different origins was evaluated by relative salt
harm rate at germination stage and by index of salt harm at seedling stage, respectively. The results indicated that salt
tolerance of germination stage of jute was consistent with that of seedling stage, with a markedly significant (P < 0.01)
correlation of 0.8432 (n =10). Two high salt tolerant genotypes (Huang No.1 and 9511) and two salt sensitive genotypes
(Mengyuan and 07-21) were screened out by these methods. Further activity analysis of POD, SOD and CAT and
determination of MDA content at seedling stage validated that genotypes Huang No.1 and 9511 were more salt tolerant than
genotypes Mengyuan and 07-21. Our results indicated that the combination of relative salt harm rate at germination stage
and index of salt harm at seedling stage can be used to evaluate salt tolerance of jute genotypes
