| 摘 要： | 在小麦背景中离果山羊草3C染色体具有优先传递的作用.当离果山羊草3C染色体处于单体状态时会导致后代不含有杀配子染色体的配子中产生包括缺失和易位等染色体结构变异.簇毛麦4V染色体携有抗小麦眼斑病和全蚀病基因.为进一步利用簇毛麦4V染色体上的有益基因.利用染色体C-分带和基因组原位杂交分析,从普通小麦-簇毛麦4V染色体二体异附加系(DA4V)与普通小麦农林26-离果山羊草3C染色体二体异附加系(DA3C)杂种后代中选育出小麦-簇毛麦纯合易住系T4VS·6AL.该易位系为杀配子染色体诱发形成的非补偿型易位;易位系T4VS·6AL高抗梭条花叶病.是小麦抗病育种的新种质.

| Abstract: | Chromosome 3C of Aegilops triuncialis were of the ability to be transferred preferentially in the case of its monosomic status in wheat background. Whereas, those gametes without 3C would result in chromosome structural changes including deletion and translocation. Eyespot and take-all resistance gene was mapped on chromosome 4V. The objective of this study was to develop more translocation lines involving chromosome 4V, and provided new germplasm for wheat breeding. Triticum aestivum-Haynaldia villosa 4V d... |
