| 摘 要： | 选取19个小麦叶锈菌生理小种对8个小麦育种亲本进行成株期和苗期抗叶锈病鉴定及基因推导,同时利用与24个抗叶锈基因紧密连锁或共分离的31个分子标记进行分子检测。推测出L83#-5与L83#-6含有Lr1,可能含有Lr2c和Lr42;L/PL2003-1含有Lr1,可能含有Lr2c、Lr28和Lr42;贵农13号可能含有Lr28;92R137可能含有Lr2c和Lr28;L201含有Lr1,可能含有Lr2c、Lr16和Lr28;TM可能含有Lr41和其他抗叶锈基因。研究结果表明,测试的8个小麦育种亲本中TM的抗叶锈性最好,具有很好的抗叶锈病应用潜力,可作为小麦抗叶锈病育种的重要抗源。

| Abstract: | Resistance evaluation and gene postulation of the eight wheat breeding parents were carried out by using 19 Puccinia triticina races with different virulent patterns at seedling stage and adult stage. 31 molecular markers closely linked or co-segregated with 24 wheat leaf rust resistance genes were used to test the 8 wheat breeding parents. The results indicated that lines L83#-5 and L83#-6 carried Lr1, might contain Lr2c or Lr42. L/PL2003-1 carried Lr1, might contain Lr2c, Lr28 or Lr42. Guinong 13 might contain Lr28. Line 92R137 might contain Lr2c or Lr28. Line L201 carried Lr1, might contain Lr2c, Lr16 or Lr28. TM carried Lr41 and unknown resistance genes. The results also indicated that the resistance of TM is the strongest in the 8 wheat accessions, and will be a good accession in wheat leaf rust resistance breeding programs. |
