摘要 为筛选出适宜石柱县的烤烟品种，对遵烟6号、湘烟5号、 CF8704、改良K326和云烟87（对照）在生育期、植物学性状、农艺性状、经济性状等方面进行比较。结果表明，CF8704具有早生快发的优势，前期生长势强，农艺性状整体表现相对适宜，经济性状指标显著高于其他品种，具有在石柱县进一步推广的价值。遵烟6号、湘烟5号叶片数多，经济性状也好于云烟87（CK），但上部叶不易成熟落黄，烤后杂色烟较多，建议进一步考证观察。改良K326不太适宜石柱高海拔地区气候特征，不建议在石柱高海拔地区推广。

Abstract In order to screen out suitable flue-cured tobacco varieties in Shizhu County，we compared growth period， agronomic traits， botanical traits， economic characters of Zunyan 6，Xiangyan 5，CF8704，improved K326 and Yunyan 87. Results showed that CF8704 had the value of further promotion in Shizhu County due to the advantages of rapid growth，the strong growth potential in the early stage，relatively suitable agronomic characters and the significantly higher economic character indexes. Zunyan 6 and Xiangyan 5 had more leaves， and better economic characters than Yunyan 87 （CK），but the upper leaves were not easy to mature and turn yellow， and there were more motley leaves. Therefore， further research and observation were suggested.The improved K326 was not suitable for the climatic characteristics of the high altitude area of Shizhu County， so it was not recommended to be popularized in the high altitude area of Shizhu County.

優良的品种是烟叶生产的重要条件，是获得优质烟叶的内在因素[1-2]。但不同的烤烟品种在不同地区有不同的适应性，生态条件的变化对烤烟品种的质量和产量有很大影响[3-4]。因此要根据当地的自然条件、耕作制度、栽培方式等具体情况来选择，筛选出满足工业需求、彰显当地特色的优质品种[5]。随着卷烟品牌结构的不断升级，卷烟工业企业对烟叶品质的要求越来越高，并朝着烟叶质量多样化和区域质量稳定性方向发展[6]。为了更好满足卷烟工业品牌发展，不断提高石柱县烤烟优质原料基地建设水平，笔者对引进的4个新品种和当地主栽品种云烟87开展品种比较试验，筛选评价出在石柱烟区适应性更强的烤烟品种，为该品种在石柱烟区进一步示范推广提供理论依据。……
