2016年黄淮海地区主栽品种抗病监测与现状分析

Resistance Monitoring and Status Analysis of the Main Maize Cultivars in Huang-Huai-Hai Region in 2016

为明确黄淮海地区玉米主栽品种对病害的抗性,对河北、河南、山东三省的主栽品种进行病害监测,并结合品种审定抗病鉴定结果对主栽品种主要病害综合分析。结果表明,2016年3个试验站未发现主栽品种发生严重病害。同一病害在黄淮海不同地区表现不同,不同省份主栽品种主要病害发生种类以及严重程度亦存在差异,其中,穗腐病山东省发生最重,河北省次之,河南省发生较轻;鞘腐病河南省发生较其他两省重;南方锈病山东省发生较其他两省重。同一主栽品种在不同地区病害表现也不同。

To clarify the disease-resistance of the main maize cultivars in Huang-Huai-Hai region, a comprehensive analysis of the leading cultivars from Hebei, Henan and Shandong provinces were conducted, according to the results of disease monitoring and resistance evaluation. The results showed that leading cultivars from three provinces did not occur serious disease in 2016. The same disease has different incidence in different provinces, and there were differences in the types and severity of major diseases in different provinces. The ear rot was regarded as a most serious disease in Shandong province, followed by Hebei and Henan provinces. Sheath rot occurred in Henan province was severe than that of Hebei and Shandong provinces, while the southern maize rust in Shandong province was more serious than the other two provinces. It is also indicated that the same leading cultivars in different provinces had different diseases.
