摘　　要：以携带稻瘟病抗性基因Pib的水稻品种津稻179为供体亲本,以徐稻3号为受体亲本,利用分子标记辅助选择(MAS)技术和系谱选育方法,改良了徐稻3号对稻瘟病的抗性。经分子标记辅助选择及人工接种苗瘟、穗颈瘟及田间自然诱发鉴定,获得了以徐稻3号为背景、抗稻瘟病性增强且农艺性状优良的4个品系。Jindao 179,a material containing the rice blast resistance gene Pib,was used as gene donor to be crossed with the rice variety Xudao 3,which was used as the recipient parent.The molecular marker-assisted selection(MAS)technology and pedigree selection method were used to develop resistance to Xudao 3.By molecular marker-assisted selection and artificial inoculation with seedling blast,panicle neck blast and field-induced identification,four lines with enhanced resistance to rice blast and excellent agronomic traits were obtained with Xudao 3 as the background.
