为寻找小麦近缘种属的抗虫基因，选取中国春（Chinese spring，CS）为背景的异源附加系材料在室内进行小麦苗期对麦长管蚜Sitobion avenae（Fabricius）的抗性鉴定，以蚜情指数为抗性评价标准。结果得到以卵穗山羊草（Aegilops geniculata）为近缘种属附加系的材料具有高抗麦长管蚜的优良性状，且抗虫基因位于1Mg、7Mg染色体上，为进一步研究该材料的抗虫基因定位提供了依据。

To find the insect-resistant genes from wheat relatives species,using aphid index as the evalution indicator,Chinese Spring heterologous addition lines were selected to identify the resistance to Sitobion avenae (Fabricius)at wheat seedling stage under laboratory conditions. Results indicate that the Aegilops geniculata chromosome addition line with high resistance to Sitobion avenae,and it was preliminarily presumed that the resistance genes come from the chromosomes of Aegilops geniculata’s 1Mg and 7Mg .
