利用回交和MAS技术改良优质两系不育系金山s-2的稻瘟病抗性
水稻 标记辅助选择(MAS) 稻瘟病 抗性 Pi-2
2009/6/10
以水稻品系5173为抗性供体亲本,通过连续回交和MAS技术将稻瘟病抗性基因Pi-2导入优质低温敏核不育系金山s-2的遗传背景中。在各世代皆利用与Pi-2紧密连锁的SSR标记SRM24对目标基因进行“前景选择”,并结合形态性状进行“背景选择”,直至BC3F 2, 获得抗病标记纯合且其它性状与金山s-2非常相似的植株9株。在BC3F 1,对中选的4个单株利用SRAP标记进行遗传背景分析表明,它们与受体...

【目的】GT-MAS:gk为抗黄曲霉菌的玉米群体,在美国作为抗源种质被释放利用,对该群体进行配合力测定与杂种优势群划分的研究,有利于外引群体在国内的有效利用和推动抗黄曲霉玉米育种工作在国内的开展。【方法】试验于2003~2005年在山西农科院谷子研究所(长治)进行;试验采用6×6不完全双列杂交的遗传设计,以6个骨干自交系为测验种对抗黄曲霉玉米群体GT-MAS:gk等6个外引群体进行配合力测定。【结...
用玉米pepc基因的特异性引物对转育pepc基因的后代材料进行分子标记辅助选育(MAS),成功地培育出与轮回亲本蜀恢881遗传相似度达97.09%~99.03%的改良蜀恢881,用此改良恢复系与3个不育系冈46A、776A、2480A形成组合。结果表明,(1)自行设计的pepc基因特异性引物能对基因进行准确的筛选,而且玉米pepc基因在新的遗传背景下能够稳定遗传和高水平表达;(2)含有pepc基因...
