摘要
对小麦品种进行麦红吸浆虫抗性鉴定及抗性机制研究是培育抗虫品种、对麦红吸浆虫实行综合治理的基础工作。本文综述了20世纪50年代以来国内外对小麦品种进行麦红吸浆虫抗性鉴定的大田自然感虫鉴定法、虫圃人工接虫鉴定法、室内鉴定法、数学模型鉴定法,以及目前抗性鉴定所应用的等级评价标准和已取得的抗性鉴定结果;详细介绍了小麦品种抗麦红吸浆虫的形态抗虫机制、避虫机制以及生化抗虫机制中营养物质和次生代谢物质与品种抗虫性的关系。大量研究结果表明,小麦品种对麦红吸浆虫的抗性主要表现在抗性品种以其独特的穗形特征及避害性来阻止其产卵或取食,或通过产生有毒的次生物质或营养上的欠缺使其取食后不能正常发育而死亡。本文还对今后的研究趋势进行了展望。
In order to carry out integrated management of the wheat blossom midge, both identification of wheat variety resistance to the wheat blossom midge and study on resistance mechanism were basic work in selecting and breeding of resistant wheat varieties. The paper summarized the identification methods about resistance of various wheat varieties to the wheat blossom midge in the field and laboratory, standard of resistance grade assessment being applied at present and research results having been achieved at home and abroad from 1950s. Resistant mechanism including evading harm, physical and chemical characteristics of wheat variety was reviewed. At the same time ,the study tendency in the future was prospected .
