【摘要】 玉米丝黑穗病是春玉米生产中的主要病害之一,在世界范围内普遍发生。利用前期研究获得的主效QTL,采用分子标记辅助选择与常规育种技术相结合方法,成功地把抗病基因区段导入到10个玉米骨干自交系中,获得一批抗病自交系。利用这些抗病自交系组配的杂交种,使玉米丝黑穗病的抗性得到大幅度提高。更多还原

【Abstract】 Head smut is a main disease of spring-sowing maize production,and is widespread all over the world. In this study,we make 10 backbone inbred lines to be head smut resistant inbred lines by using normal breeding and molecular markers methods.The resistance of the hybrid seeds by using these head smut resistant inbred lines are all highly raised.更多还原
