褐飞虱是水稻的主要害虫。寄主植物抗性是治理褐飞虱最理想和最经济的策略。迄今为止，已从栽培稻和野生稻中鉴定出29个抗褐飞虱的主效基因，其中10多个基因已被精细定位在200 kb以下的染色体区域。已克隆了4个基因（Bph 14、Bph 26、Bph 17和bph 29）。越来越多的精细定位和克隆的基因为开发用于育种的功能标记提供了坚实的基础。利用分子标记辅助回交育种技术，获得了一批抗褐飞虱的导入系、近等基因系和转基因系。本文综述了水稻抗褐飞虱遗传和分子育种的研究进展。并对培育持久、广谱抗褐飞虱品种的前景进行了讨论。
Brown planthopper (BPH) is the most devastating pest of rice. Host-plant resistance is the most desirable and economic strategy in the management of BPH. To date, 29 major BPH resistance genes have been identified fromindicacultivars and wild rice species, and more than ten genes have been fine mapped to chromosome regions of less than 200 kb. Four genes (Bph14,Bph26,Bph17andbph29) have been cloned. The increasing number of fine-mapped and cloned genes provide a solid foundation for development of functional markers for use in breeding. Several BPH resistant introgression lines (ILs), near-isogenic lines (NILs) and pyramided lines (PLs) carrying single or multiple resistance genes were developed by marker assisted backcross breeding (MABC). Here we review recent progress on the genetics and molecular breeding of BPH resistance in rice. Prospect for developing cultivars with durable, broad-spectrum BPH resistance are discussed.
