Abstract:Salinity is a major limitation to crop production in coastal region. Breeding for salinity tolerance could be an effective way of improving yield and yield stability on saline-alkaline soils. However, these require a good understanding of the inheritance of this trait and occupy massive amounts of elite genetics resources tolerant to salt-stress. To provide elite germplasm for new varieties tolerant to salinity in wheat breeding, 363 accessions were evaluated for salt tolerance at the germination stage using artificial sea water. Among accessions tested，28 wheat cultivars with salt tolerance grade 1 were identified. To obtain further salt-tolerant accession at the seedling stage, 48 wheat accessions were selected from the salt tolerance resources ( grade 1 or grade 2 ) at the germination stage to evaluate salt-tolerant at the seedling stage. Two wheat accessions with high salt-tolerant were screened by using the methods of fuzzy membership function. They were Huaimai 31 and Hongkeyangmai, respectively. Based on the original of the wheat germplasm, the capacity of salinity tolerance was different: local varieties>improved varieties>introduced varieties. Correlation analysis of wheat salt tolerance at the germination stage and the seedling stage showed that there is no consistent correlation existed.
