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。
In order to breed new flue-cured tobacco varieties resistant to TMV and climate spot disease, male sterile line K326 with high quality flue-cured tobacco as female parent, K8, a breeding intermediate material with high resistance to TMV and climate spot, was used as male parent, Flue-cured tobacco varieties Shennong 1. The results showed that this variety is more adaptable and resistant to TMV, high resistance to climate spot, black shank and brown spot disease, light bacterial wilt, root-knot nematode disease, CMV and PVY, and its comprehensive disease resistance is better than K326 ; After the roast, the tobacco had golden yellow color, loose leaf structure, moderate identity and more oil; the original tobacco contained relatively low stems with relatively high single leaf quality; the main chemical components were suitable and the proportion was more harmonious; the fragrance quality was better , Aroma more abundant, more rhyme rhyme, more comfortable aftertaste, more obvious sweetness, balanced index, superior availability of upper tobacco; comprehensive economic traits better than the control K326; is a quality, yield, economic benefits, adaptability , Resistance and other aspects can take into account the good new varieties of tobacco.
