| 中文摘要: |
| 种植抗病品种是防治小麦条锈最经济有效且有利于环境保护的措施。2016年－2018年,在甘肃陇南两个不同生态区甘谷和汪川试验点对8个中梁系列冬小麦品种‘中梁25号’~‘中梁32号’进行了成株期抗条锈性分析,并在温室进行了苗期抗条锈病性评价。成株期抗条锈性鉴定结果表明:‘中梁25号’~‘中梁28号’对接种及自然诱发的条锈菌单孢菌系及混合菌均表现感病;‘中梁29号’对条锈菌CYR32、CYR33、中4-1表现抗病,对条锈菌CYR34和G22-14表现中抗~中感;‘中梁30号’~‘中梁32号’对供试条锈菌单孢菌系及混合菌表现免疫到中抗。抗条锈病基因检测发现:‘中梁26号’和‘中梁27号’含有抗病基因Yr9,‘中梁29号’含有抗病基因Yr26,其余品种含有未知抗条锈病基因。同时对后CYR34时期供试品种在甘肃陇南的利用前景进行了讨论。 |

| Wheat stripe rust, caused by Puccinia striiformis f.sp. tritici (Pst), is one of the most destructive diseases in wheat in Longnan, Gansu province and China. Planting resistant wheat varieties is one of the most economical, environment friendly and effective methods to control wheat stripe rust in field. The seedling stage and adult-plant stage resistance of eight winter wheat varieties, ‘Zhongliang 25’ to ‘Zhongliang 32’ were identified by artificial inoculation of different races/isolates of Pst (CYR32, CYR33, CYR 34, G22-14 and Zhong 4-1) and mixtures of Pst in low-temperature greenhouse in Lanzhou and Gangu testing station during 2016-2018. Meanwhile, the adult-plant stage resistance of varieties was also evaluated in the field of Gangu and Wangchuan testing station. The results showed that ‘Zhongliang 25’, ‘Zhongliang 26’, ‘Zhongliang 27’and ‘Zhongliang 28’ were susceptible to the tested races/isolates and the mixtures of natural isolates in all-stage. The ‘Zhongliang 29’ showed moderate resistance to moderate susceptible against CYR 34, G22-14 and resistant to CYR32, CYR33 and Zhong 4-1. The ‘Zhongliang 30’, ‘Zhongliang 31’ and ‘Zhongliang 32’ showed immune to resistant to tested single and mixed isolates of Pst in all-stage. Molecular detection of resistant Yr genes showed that the ‘Zhongliang 26’ and ‘Zhongliang 27’ had Yr9, ‘Zhongliang 29’ had Yr26, and other wheat varieties had unknown resistant genes. Application prospect of these wheat varieties at CYR34 post stage was discussed. |
