| 为了解小麦品种（系）在孕穗期和灌浆期的田间抗蚜表现，本研究在自然感蚜的条件下，于2010/2011和2011/2012年度分别在孕穗期和灌浆期对148份小麦品种（系）进行田间抗蚜性调查，采用蚜量比值法对品种（系）抗蚜性进行了评价。结果表明，孕穗期抗蚜性表现为高抗水平的小麦品种（系）有：衡6632、农大3432和京冬8号，占品种总数的2.03%；灌浆期表现为抗性或中抗水平的品种有：漯麦4号、邯6228、邯4015、KOK1679、烟农23、京花1号、临抗15和扬麦158等8个品种，占5.41%；在孕穗期和灌浆期均表现为中抗水平以上的有：08P20、KOK1679、衡6632、冀38、临抗15号和漯麦4号等6个品种，占4.05%。本研究可为下一步抗蚜（耐蚜）亲本材料的筛选和新品种培育提供参考。 |

| Abstract: |
| In order to explore the aphid-resistance of wheat cultivars/lines at booting and filling stage in the fields,and then offer the reference for selecting parents and breeding new aphid-resistant cultivars effectively,the resistance to aphid of 148 wheat cultivars/lines in natural susceptible conditions in 2010/2011 and 2011/2012 years in Beijing area were studied using the aphid number ratio method.The results showed that Heng6632,Nongda3432 and Jingdong8 had high resistance at the booting stage;Luomai4,Han6228,Han4015,KOK1679,Yannong23,Jinghua1,Linkang15 and Yangmai158 had resistance or mid-resistance at filling stage.Meanwhile 08P20,KOK1679,Heng6632,Ji38、Linkang15 and Luomai4 had mid-resistance or above at both stage. |
