| ［目的］ 明确不同小麦品种对麦长管蚜(Sitobion avenae)的室内苗期抗性。［方法］ 在温室内采用每株小麦接种1头蚜虫的方法，测定了麦长管蚜在来源于3个国家的10个小麦品种上的发育历期（DD）、相对日均体重增长量（MRGR）和成虫日均产仔数（Rm），以此来确定不同小麦品种（材料）的抗蚜性。［结果］ 应用多元方差分析，多目标综合判别及聚类分析等方法分析表明，麦长管蚜在‘Ww2730’、‘98 10 30’、‘Astron’上的适应性最差，这几个品种对其抗性最好，是可以利用的抗性品种（材料）；‘98 10 35’、‘98 10 32’次之；‘Batis’对麦长管蚜的适应性最好，抗性最差；‘186Tm’，‘Xanthus’，‘Amigo’对麦长管蚜适应性较好，与作为对照的‘小偃 22’一样，抗性处在中间水平。［结论］ 研究结果可以为进一步的抗蚜育种提供依据。 |

| ［Objective］ To understand the resistance mechanism of different wheat varieties to Sitobion avenae at wheat seedling stage. ［Method］ Ten wheat varieties or hybrid progenies of the wheat Triticum sativum and einkorn Triticum monococcum L., or wheat and quack grass Agropyrum repens Beauvois from Germany, China and America were evaluated for their resistance to the cereal aphid S. avenae in seedlings in glasshouses. Three biological parameters, including development days (DD), mean relative growth rate (MRGR) and rate of mean production (Rm), were used as the indicators for the level of plant resistance. ［Result］ Based on multivariate variance analysis, multi objective integrated evaluation and cluster analysis, the results indicated that ‘Ww2730’, ‘98 10 30’ and ‘Astron’ had the highest resistance to S. avenae, followed by ‘98 10 35’ and ‘98 10 32’. The first three varieties could be used as the resistant resources to S. avenae in wheat breeding. ‘Batis’ had the lowest resistance.［Conclusion］ The results may provide a basis for resistance breeding to aphids. |
