摘要
为选育抗烟草普通花叶病毒病(Tobacco mosaic virus,TMV)的烤烟新品种,以优质烤烟品种中烟103的雄性不育系为母本,高抗TMV的育种中间材料K8为父本,采用杂交技术选育出烤烟品种鄂烤2号。结果表明,鄂烤2号中抗黑胫病和根结线虫病,对TMV免疫,且高抗气候斑点病,综合抗病性优于对照品种(K326和云烟87),适应性较强;烤后原烟颜色多金黄,叶片结构疏松,身份适中,油分较多;原烟单叶质量相对较高;主要化学成分含量适宜,比例较协调;烟叶感官评吸质量档次中等偏上,整体吸食品质优于对照品种;综合经济性状优于K326和云烟87。鄂烤2号是一个品质、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。
To breed new tobacco varieties with resistance to tobacco mosaic virus（TMV）, a new flue-cured tobacco cv. Ekao No.2 was bred with a male sterile line of Zhongyan 103（a quality flue-cured female variety）and K8（a male breeding intermediate with high resistance to TMV） as the parents, respectively. The results showed that Ekao No.2 possessed a moderate resistance to black shank and root knot nematode, immunity to TMV, and high resistance to climate spot disease. With improved adaptability, the comprehensive disease resistance of Ekao No.2 was better than that of the control varieties（K326 and Yunyan 87）. The flue-cured leaves of Ekao No.2 displayed well-distributed golden color and were loose in structure, moderate in body and rich in oil. Its single leaf weight was relatively high, the contents of main chemical components were harmonious, the sensory quality was above moderate. Ekao No.2 was better in comprehensive smoking quality comparing with K326 and Yunyan 87. Therefore, Ekao No.2 could be considered as a new variety with balanced potentials for high quality, good productivity, economic performance, wide adaptability and strong resistance to diseases.
