摘要
为选育抗TMV和气候斑点病的烤烟新品种,以优质烤烟品种K326的雄性不育系为母本,高抗TMV和气候斑点病的育种中间材料K8为父本,采用杂交技术选育出烤烟品种金神农1号。试验结果表明,该品种适应性强,对TMV免疫,高抗气候斑点病,抗黑胫病和赤星病,轻感青枯病、根结线虫病、CMV和PVY,综合抗病性优于K326;烤后原烟多金黄色,叶片结构疏松,身份适中,油分较多;原烟含梗率相对较低,单叶质量相对较高;主要化学成分含量适宜,比例较协调;香气质较好,香气量较足,香韵较丰富,余味较舒适,甜感较明显,各项指标均衡,上部烟可用性较强;综合经济性状优于对照K326;是一个品质、产量、经济效益、适应性、抗性等方面较能兼顾的优良烤烟新品种。
For breeding new varieties with resistance to TMV and climate spot disease,a new flue-cured tobaccocv.Jinshennong No.1 was bred with K326（quality flue-cured female variety） and K8（a male breedingintermediate with high resistance to TMV and climate spot disease） as parents,respectively.The experimentalresults showed that Jinshennong No.1 possessed good adaptability,immunity to TMV,high resistance to climatespot disease,resistance to black shank and Alternaria alternate,and slight infection to bacterial wilt,root knotnematode,CMV and PVY.The comprehensive disease resistance of this new variety was better than K326.Theflue-cured leaves of Jinshennong No.1 were rich in oil,loose in structure and moderate in body,and displayed well-distributed golden color.Its stem content was relatively lower,single leaf weight was relatively higher,andthe contents of main chemical components were harmonious with better aroma quality,plentiful aroma quantity,rich flavor note,comfortable aftertaste and obvious sweet taste,hence the usability of upper leaves was good.Comparing with K326,the new variety was better in comprehensive economic characters.In conclusion,Jinshennong No.1 is a new variety with potentials for high quality,good productivity,remarkable economicperformance,wide adaptability and strong resistance to diseases.
