2015年采取田间自然诱发鉴定方法,分析44个主栽玉米品种对玉米锈病的抗性,明确聊城地区主栽玉米品种对锈病的抗感性差异。结果表明,不同玉米品种对玉米锈病抗性差异明显,易感病品种偏多,为54.54%(高感品种占40.91%,感病品种占13.63%);较抗病品种占36.37%(高抗品种占22.73%,抗病品种占13.64%)。大量易感品种的推广是造成玉米锈病流行的主要原因,应大力推广聊玉23、诺达1号、德单5号、登海605、鲁宁184等高抗品种。
In 2015, the natural induced identification method was adopted to analyze the resistance of 44 main maize cultivars to the rust of corn and the difference of anti-rust susceptibility of the main maize cultivars in Liaocheng to rust. The results showed that the resistance of different maize cultivars was significantly different from that of the susceptible ones, with 54.54% of the susceptible varieties (40.91% of the susceptible cultivars and 13.63% of the susceptible cultivars), 36.37% of the susceptible cultivars Varieties accounted for 22.73%, resistant varieties accounted for 13.64%). The promotion of a large number of susceptible varieties is the main cause of the epidemic of corn rust should be vigorously promote Liaoyu 23, Noida 1, Germany and Germany No. 5, Denghai 605, Lunin 184 and other high resistant varieties.
