为明确玉米不同品种（系）之间的抗螟性差异，采用田间自然感螟法，于2010～2011年在甘肃省天水市甘谷县对478份玉米种质资源进行田间抗性鉴定。结果表明：在216份农家种资源、216份自交系和46份杂交种中共筛选出高抗材料86份、抗螟材料85份、中抗材料167份，分别占供鉴材料的18．0％、17．8％和34．9％；其余140份为感螟和高感材料，占29．3％。
為明確玉米不同品種（繫）之間的抗螟性差異，採用田間自然感螟法，于2010～2011年在甘肅省天水市甘穀縣對478份玉米種質資源進行田間抗性鑒定。結果錶明：在216份農傢種資源、216份自交繫和46份雜交種中共篩選齣高抗材料86份、抗螟材料85份、中抗材料167份，分彆佔供鑒材料的18．0％、17．8％和34．9％；其餘140份為感螟和高感材料，佔29．3％。

So as to confirm the borer-resistance differences among different corn varieties ( inbred lines ) , the study adopted the method of being naturally infected by Ostrinia furnacalis under field conditions , and identified the resistance of 478 maize germ-plasms to corn borer in Gan ’ gu county, Tianshui city, Gansu province from 2010 to 2012.The results showed that: among 478 maize germplasms (216 peasant variety resources , 216 inbred lines and 46 hybrids), 86 high-resistant materials (18.0% of all materials), 85 borer-resistant materials (17.8%), 167 middle-resistant materials (34.9%) were screened out;the other 140 materials were susceptible or highly susceptible to corn borer , accounting for 29.3%of all tested materials.
