摘 要: | 目的]为进一步利用簇毛麦2V染色体上的有益基因,为小麦育种提供新种质。方法]通过普通小麦-簇毛麦2V(2D)二体代换系(DS2V)与普通小麦农林26-离果山羊草3C染色体二体异附加系(DA3C)杂交,综合运用染色体C-分带、基因组原位杂交和分子标记分析,并结合性状调查。结果]从杂种后代中选育出小麦-簇毛麦纯合易位系T6BS.6BL-2VS,性状调查发现该易位系植株护颖颖脊上有刚毛。结论]该易位系为杀配子染色体诱发的小片段易位;簇毛麦护颖颖脊刚毛基因定位于2VS的中部至端部。

Abstract: | Objective] The aim of experiment was to provide a new germplasm for wheat breeding by further using desirable genes in 2V chromosome of Haynaldia villosa.Method] Through hybridization between common wheat(Triticum aestivum)-Haynaldia villosa disomic substitution line and common wheat Nonglin26-3C chromosome of Aegilops triuncialis disomic addition line,the analysis methods such as chromosome C-banding,genomic in situ hybridization and molecular marker technique were comprehensively applied and combined characters investigation.Result] The wheat-Haynaldia villosa translocation line(T6BS·6BL-2VS) was selected from hybrid progenies to conduct characters investigation,which found some bristles on glume ridge of T6BS·6BL-2VS.Conclusion] The translocation line induced by gametocidal chromosome was a small segment translocation line and the gene of bristle on glume ridge of Haynaldia villosa was located between the middle and the terminal of 2VS. |
