水稻抗稻瘿蚊遗传育种研究进展

Recent advance in the genetic study and breeding of gall midge resistance in rice

稻瘿蚊是亚州稻区主要害虫之一 ,采用抗虫品种进行防治是最理想的办法 ,而抗稻瘿蚊品种的收集和鉴定、抗虫机制的研究、抗性的遗传分析和抗性基因的分子标记定位等方面研究对抗稻瘿蚊品种的选育和应用具有十分重要的意义 .本文就上述几方面的研究现状作一概述 。

Rice gall midge ( Orscolia oryzae ) is an important pest of rice( Oryza sativa L.) in Asia. Planting resistant varieties to control this pest has been proved to be the most ideal measure. The study of the recent development of collection and identification of varieties resistant to gall midge, mechanism of resistance to gall midge, genetic analysis and gene location of the resistant genes is essential to the breeding and application of resistant varieties. The current situation in these aspects is reviewed in the paper. In addition, the present problems and strategy are also discussed.
