| 摘 要： | 麦根腐平脐蠕孢菌Bipolaris sorokiniana(Sacc.)Shoemaker]引起的叶斑病是大麦上重要的病害叶部之一,在世界各大麦主要种植区均能造成严重的经济损失。本研究利用3个致病力不同的蠕孢叶斑病菌株Z 12010、Z 12014和Z 13010分别对来源于中国及国外引进的61份大麦种质资源进行苗期抗蠕孢菌叶斑病鉴定,田间接种Z 12014菌株进行成株期抗病性鉴定。在所鉴定的大麦种质中未发现在苗期或成株期对叶斑病免疫的材料。苗期抗叶斑病分析发现,品种之间对3个菌株的抗性存在明显差异,Varunda、Legacy、Tradition、09GW-01、09GW-07、08PJ-36、09PJ-39、垦啤麦7号、垦啤麦10号、驻大麦3号、S-4和中饲麦1号等12份材料对3个菌株表现为中抗至高抗反应型。7份材料成株期抗Z 12014菌株,其中Legacy、蒙啤麦3号、09PJ-39、垦啤麦9号、垦啤麦11号和龙啤麦3号等6份材料具有全生育期抗性特点,品种10-3苗期对菌株Z 12014感病,而成株期抗该菌株。 |

| Abstract: | Spot blotch, caused by the fungal pathogen Bipolaris sorokiniana (Sacc.) Shoemaker, is one of the important foliar diseases on barley, which can cause serious yield losses in the barley-growing regions worldwide. In this study, three Bs isolates (Z 12010, Z 12014, and Z 13010) with different patterns of pathogenicity were used to test the spot blotch resistance of 61 barley germplasm accessions collected from China and other countries at the seedling stage. The adult-plant resistance to spot blotch in this set of barley germplasms was evaluated by inoculating isolate Z 12014 in the field. There was no barley accession showing immune reaction to spot blotch. Significant difference in the seedling resistance were found among the accessions against the three pathogenic isolates. Twelve accessions, Varunda, Legacy, Tradition, 09GW-01, 09GW-07, 08PJ-36, 09PJ-39, Kenpimai 7, Kenpimai 10, Zhudamai 3, S-4, and Zhongsimai 1, were moderately or highly resistant to the three isolates examined. Seven barley accessions were resistant to isolate Z 12014 at the adult-plant stage, of which 6 accessions, Legacy, Mengpimai 3, 09PJ-39, Kenpimai 9, Kenpimai 11, and Longpimai 3, showed all-stage resistance, and variety 10-3 was susceptible at the seedling stage but resistant at the adult-plant stage to isolate Z 12014. |
