摘要: 亚洲玉米螟是为害玉米的一种重要害虫,利用抗性品种是有效控制玉米螟为害的最经济有效的方法。2016年在安徽凤阳和海南乐东评价了1 463个普通玉米自交系对亚洲玉米螟的抗性水平,并测量这些自交系的理化性状,包括株高、穗位高、叶片数、穗三叶长、穗三叶宽、穗三叶夹角、茎粗、叶片厚度、叶片硬度、蜡质含量、单宁、可溶性糖、可溶性蛋白含量等理化性状,分析了理化性状与抗螟性的相关性。鉴定结果显示,高抗自交系142个,抗性自交系317个,中抗自交系322个,抗虫自交系占53.38%;相关性分析表明,玉米株高、穗位高、叶片数、叶长、叶宽、叶夹角、10 cm茎粗、叶片蜡质含量与其抗螟性无显著相关,而叶片厚度、叶片硬度、单宁含量、可溶性糖、可溶性蛋白含量与玉米抗螟性显著相关。

Abstract: Asian corn borer, Ostrinia furnacalis, is an important maize pest. The most economical and effective measurement to control it was to breed resistant varieties. In 2016, the resistance level of 1 463 common maize inbred lines to maize borer was evaluated in Fengyang, Anhui and Ledong, Hainan. At the same time, the physicochemical characters, such as plant height, ear height, leaf number, length, width and angle of spike three leaves, stem diameter, leaf thickness, leaf hardness, tannin content, wax content, soluble sugar and soluble protein content, were measured. The relationship between borer resistance and physicochemical characters was analyzed. The identification results showed as follows: there were 142 highly-resistant inbred lines, 317 resistant inbred lines and 322 mid-resistant inbred lines and zoophobocus inbred lines accounted for 53.38%. Correlation analysis showed that the plant height, ear height, leaf number, leaf length, leaf width, leaf angle, stem diameter, and wax content of maize inbred lines were not significantly related to borer resistance. However, the leaf thickness, leaf hardness, tannin content, soluble sugar and soluble protein content were significantly correlated with maize resistance.

Key words: maize inbred line, Ostrinia furnacalis, resistance identification, resistance mechanism
