| 摘 要： | 为加快SDS沉降值在小麦品质改良中的应用,对来自小麦微核心种质中的83份育成品种和146份地方品种的SDS沉降值进行了测定,初步分析了SDS沉降值的遗传多样性及分布规律。结果表明,育成品种和地方品种的SDS沉降值基因型间差异极显著,具有较大的变幅和变异系数;两种类型小麦种质的SDS沉降值均主要分布在25.0～35.0ml,SDS沉降值>45ml和SDS沉降值<15ml的种质所占比例较小;SDS沉降值最高与最低的种质均来自地方品种,分别为白朗灰麦和假红麦,育成品种中SDS沉降值最高与最低的种质分别为东方红3号和农大139。根据SDS沉降值的分布,筛选了7份高SDS沉降值和8份低SDS沉降值的种质,这些种质可作为高、低SDS沉降值小麦品种选育的中间材料加以利用。

| Abstract: | To accelerate the application of SDS sedimentation volume in wheat quality improvement,the SDS sedimentation volumes of 83 bred varieties and 146 local varieties of Chinese wheat micro-core collections were measured,and a preliminary analysis of the genetic diversity and distribution of SDS sedimentation volume was done.The results indicated that: there were significant differences in SDS sedimentation volume of bred and local varieties between genotypes,and SDS-sedimentation volumes of the two varieties we... |
