    摘要:

    本试验对 121 份小麦等材料的耐盐性进行综合评价,以期为小麦耐盐生理、遗传育种等研究提供参考。结果表明, 根据耐盐性将供试材料分为五类:高耐盐材料(P13、C1009、1710、1713 和 082-1,D 值 0.5877~0.6616);耐盐材料(1706、 081、0819-1、PSR3628 和 TB1 等 9 份种质,D 值 0.4222~0.5331);中耐盐材料(1707、1805、TPF8、1704 和 1712 等 41 份 种质,D 值 0.2684~0.3940);盐敏感材料(45 份种质,D 值 0.1922~0.2640);高盐敏感材料(21 份种质,D 值 0.0504~ 0.1848)。偏凸山羊草×硬粒小麦衍生系中 P13、082-1、081、082-2 材料的 D 值分布在 0.4231~0.6616,表现为高耐或耐 盐。一粒小麦×葡萄牙野燕麦衍生系,提莫菲维小麦×葡萄牙野燕麦衍生系的 D 值均值分别为 0.4145 和 0.4106,显著大于 普通小麦群体,它们总体上表现耐盐。8 个小麦远缘杂交后代群体 D 值均值大于普通小麦群体,筛选出 P13、1713、082-1、 1706 和 081 等耐盐新种质。

    Abstract:

    One-hundred twenty-one wheat germplasm accessions derived from distant hybridization were tested for salt-tolerance, in order to provide insight for salt-tolerant physiology, genetics and breeding in wheat. Based on D value, these materials were classified into five categories: highly salt-tolerant (five genotypes including P13, C1009, 1710, 1713 and 082-1, D value from 0.5877 to 0.6616); salt-tolerant (nine genotypes such as 1706, 081, 0819-1, PSR3628, TB1, D value ranged from 0.4222 to 0.5331); moderate salt-tolerant (41 genotypes such as 1707, 1805, TPF8, 1704, 1712, with a D value of 0.2684 to 0.3940); salt-sensitive (45 genotypes, with a D value of 0.1922 to 0.2640) ; highly salt-sensitive (21 genotypes, with a D value of 0.0504-0.1848). Especially, the D values of P13, 082-1, 081 and 082-2 lines derived from the cross Aegilops ventricosa × durum wheat ranged from 0.4231 to 0.6616, which showed high salt-tolerance or salt-tolerance. The average D values of the derivatives from einkorn wheat × Avena Fatua L.Var.Portugal, and T. timopheevii × Avena Fatua L. Var. Portugal were 0.4145 and 0.4106, which were significantly higher than that of common wheat accessions. The average D values of 8 progeny populations from wheat distant crosses were higher than that of common wheat. Finally, a few of new salt-tolerant germplasm accessions (i.e. P13, 1713, 082-1, 1706, 081) were identified.
