【摘要】 在3种不同盐胁迫浓度下对161份来源于西藏的小麦材料进行了苗期耐盐性鉴定,其中有147份西藏半野生小麦及14份密穗小麦。以普通小麦耐盐品种茶淀红麦和盐敏感品种 P194341为对照。在147份西藏半野生小麦中有14份表现为耐盐,占9.5%。14份密穗小麦中没有发现耐盐材料。在这161份材料中还发现了3份对盐胁迫浓度梯度不敏感的品种。结果表明,我国特有的西藏半野生小麦中蕴藏有丰富的耐盐种质,它们可供小麦耐盐育种用做亲本。更多还原

【Abstract】 One hundred and sixty one Tibetan wheat accessions were identified for salt tolerance under three different salt concentrations.Salt-tolerant variety Chadianhong and sah-sensitive variety PI94341 were used as CK varieties.Fourteen accessions with better salt tolerance were selected.Three salt insensitive accessions were found.The results showed that Tibetan wheat is rich in salt tolerant genotypes.These sah-tolerant germplasm of Tibetan wheat will become important material basis for salt-tolerant wheat breeding.更多还原
