| 摘 要： | 为了简化小麦品种对麦红吸浆虫抗性的鉴定方法，评价我国冬小麦主栽品种对吸浆虫的抗感性，2008-2012年在河南洛阳田间，连续调查鉴定麦红吸浆虫对我国小麦主栽品种的虫穗率(ISP)与损失率，分析其相关性。结果表明ISP和损失率存在显著的相关性。在田间吸浆虫高密度下，ISP定级方法比相对定级方法更能表现品种的抗性和敏感程度，各抗级的指标依次为0 (免疫)、0 < ISP < 20 (高抗)、20 ≤ ISP < 40 (中抗)、40 ≤ ISP < 60 (中级)、60 ≤ ISP < 80 (感)和ISP ≥ 80 (高感)。我国冬小麦的主要生产品种对吸浆虫均为感虫或高感，而荆麦66表现为高抗，我国小麦中极度缺乏抗虫品种。鉴定结果表明，ISP定级方法简便高效，可以取代相对定级法用于小麦抗红吸浆虫的鉴定。

| Abstract: | To simplify the method of identifying resistance in winter wheat varieties to orange wheat blossom midge,Sitodiplosis mosellana (Diptera: Cecidomyidae), we compared the traditional method for resistance assessment and a resistance grading method based on percentage of infested spike (ISP) in field experiments carried out in Luoyang, Henan Province, China from 2008 to 2012, using 236–417 wheat varieties each year. The correlation analysis showed that yield loss was highly associated with ISP. Under high density of insect population, the ISP grading method was more effective in identifying the resistance to the insect than the traditional method, and the resistance to S. mosellana was divided into five levels, namely immune (ISP = 0), highly resistant (0 < ISP < 20), moderately resistant (20 £ ISP < 40), Medium (40 £ ISP < 60), susceptible (60 £ ISP < 80), and highly susceptible (ISP ≥ 80). Using ISP grading method, resistance to S. mosellana was evaluated in 25 commercial wheat varieties with growing area larger than 2´105 hectares. All varieties of winter wheat were susceptible or highly susceptible to S. mosellana, but Jingmai 66, was highly resistant. This result indicates not only the possibility of replacement of the traditional resistance evaluation method by the new simple and high-efficient grading method, but also the risk of S. mosellana burst due to extreme shortage of resistant resource in Chinese wheat varieties. |
