摘要
Mo17玉米自交系具有高产、稳产、耐瘠性强、适应性广等特点,由其所组配的玉米杂交种在我国的玉米生产中产生了极其重要的作用。如中单2号、丹玉13、本育9号和烟单14等,这些玉米杂交种种植区域从南到北,从东到西都有种植的历史。随着时间流逝,Mo17玉米自交系明显表现出易感大小斑病、早衰等退化现象。针对上述现象,全国各育种单位先后选育出优良Mo17衍生系,如吉846、吉842、丹1324、龙抗11、4F1、419和495等,这些玉米自交系所组配的杂交种表现出稳产性好、抗病性强、适应性广的优点,深受吉林、黑龙江、内蒙古自治区和辽宁东部山区农民欢迎。
Maize self in b red line of Mo17has the character of high and steady grain yield,high enduran ce to barren,wide adapta-tion etc.The hybrids crossed by Mo17such as Zhongd an2,Danyu13,Benyu9,Yandan14etc,which have played very important roles in the maize production in all maize planting areas of China.After a long term of planting,maize self inbred line Mo17put up the phe-nomenon of sensitivity to the Northern and Southern blots and early death.For this case,the Mo17de riving self-inbred lines such as Ji846,Ji842,Dan1324,Longkang11 ,4F1,419,495etc have been bred in many maize breeding units in China .The hybrids crossed by the Mo17deriving self-inbred lines have the characte r of steady yield,high resistance to diseases,wide adaptation and are welcomed by the users of Jilin,Heilongjiang and Liaoning provinces and the farmers of I nner Mongolia Municipality.
