| 摘要: |
| 将粗厚山羊草（6X）、牡山羊草、瓦维洛夫山羊草等D2型异源细胞质导入普通小麦，研究它们对普通小麦籽粒品质的的影响。结果表明，D2型细胞质对提高蛋白质和湿面筋含量的作用很明显；对干面筋含量的影响因品种本身含量高低而不同，对低面筋含量品种的提高作用较大；对沉淀值的影响主要因核型不同而异。认为将D2型异源细胞质导入普通小麦是一条有效的品质改良途径。 |

| Influence of the D2 Type Alloplasm on Wheat Quality |

| Abstract: |
| The grain weight,sedimentation,protein and gluten content were studied by transfering D2 type cytoplasm of Ae. crassa (6x),Ae. juvenalis and Ae. vavilovii into wheat.The results showed that the cytoplasm of D2 type cytoplasm increased the protein and wet gluten content in wheat obviously.The influence on dry gluten content differed with the content of variety.The dry gluten content could be increased obviously if the content of variety itself was low.In some nucleus backgrounds the sedimentation was increased,but in others it was reduced.The results indicated that it was an effective way for improving quality to transfer the cytoplasm of D2 type into wheat. |
