We found significant but various depressing levels of germination rate under salt stress among different germplasms, and only 5% of 128 germplasms were highly resistant to salinity. We also found that the relative germination index was a useful evaluation index for salt tolerance besides salt damage rate and rela- tive germination rate. After all, we comprehensively screened out 7 materials (JS011, JS024, JS125, JS491, JS523, JS524 and JS525) as salt tolerance germplasms for further research. Key展开更多
