亚洲稻瘿蚊(Orseolia oryzae Wood-Mason)是华南的主要水稻害虫.选育抗虫品种是最有效的生态控制方法。本文综述1998-2006年抗性育种的进展。用AFLP方法对从中国广东省7个地点采集的4个生物型的DAN指纹进行分析;在对用RAPD和SSR技术分别对抗中国4个稻瘿蚊生物型的基因Gm6精细定位基础上,用与Gm6紧密连锁的STS和SSR标记开展分子标记辅助育种,创造了一批抗稻瘿蚊的新种质,包括育成了6个栽培稻和6个二系杂交稻和1个三系杂交稻并在农户试种,在中国广东成功地建立了分子标记辅助选育抗稻瘿蚊品种的技术体系。
Orseolia oryzae Wood-Mason is a major rice pest in southern China, and breeding insect-resistant varieties is the most effective ecological control method. This article reviews the progress of resistance breeding in 1998-2006. AFLP method was used to analyze four biotypes of DAN fingerprints collected from seven sites in Guangdong Province, China. Based on the precise mapping of Gm6 loci against four Chinese rice gall midge biotypes using RAPD and SSR techniques, Gm6 tightly linked STS and SSR markers were used for molecular marker-assisted breeding to create a new germplasm of resistance to Gallid mosquito, including the breeding of 6 cultivated and 6 second-line and one 3-line hybrid rice Farmers planted their crops and successfully established a molecular marker-assisted breeding system against rice gall midge in Guangdong, China.
