Abstract:
利用高抗条锈病的小麦?偏凸山羊草6mv/6b代换系(moisson6mv/6b)与高感条锈病的四川小麦绵阳26、绵阳93-124和sw3243进行杂交,并用这些品种分别与杂种f1进行正反回交,通过对其f1、f2和bc1的结实率观察、细胞学分析以及条锈病抗性反应鉴定,研究了偏凸山羊草6mv染色体在不同四川小麦背景中的传递频率,分析了代换染色体6mv代偿6b的能力.结果显示,当含6mv染色体的f1植株作母本时,平均回交结实率为83.10%,最高可达95.51%;而含6mv染色体的f1植株作父本时,平均回交结实率则为48.61%,最低仅为28.47%,暗示6mv染色体可能对花粉参与受精的能力有一定不利影响,且结实率与小麦基因型相关.在与绵阳26、绵阳93-124和sw3243的所有杂交组合中,6mv染色体通过雌、雄配子的传递率没有显著差异,但其传递率与小麦品种显著相关.另外,在单体代换植株中6mv染色体通过自交的传递率也受小麦品种基因型的影响.研究结果为小麦?偏凸山羊草6mv/6b代换系在小麦育种上的利用提供了理论依据.图1表4参15
