摘要 [目的]筛选出适宜永州烟区种植的优良品种。[方法]以MSK326、云烟87为对照，在永州烟区对国外引进的7个品种（系）进行的植物学性状、农艺性状、烟叶经济性状及烟叶外观质量等多方面的比较试验。[结果]NC-YATAS101表现较好，其产量、产值、均价等经济性状比较均衡，产值、上等烟指标高于对照MSK326和云烟87，烤后烟总体外观质量较好;其次是NC-YATAS102，其产量、产值、上等烟等经济性状指标高于云烟87，总体外观质量偏好，化学成分的协调性较理想。[结论]建议2020年可将NC-YATAS101在永州市部分烟区作小面积生产试验示范，作为后备品种。

Abstract [Objective] To screen out suitable varieties of flue-cured tobacco in Yongzhou tobacco growing area. [Method] With MSK326 and Yunyan 87 as controls， comparative tests on botanical traits， agronomic traits， economic traits of tobacco leaves and appearance quality of tobacco were conducted in Yongzhou tobacco-growing areas for seven varieties（lines） introduced from abroad. [Result] The better-performing line is NC-YATAS101. Its economic characteristics， such as yield， output value and average price were more balanced. The output value and first-rate tobacco indicators were higher than the control MSK326 and Yunyan 87. The overall appearance quality of flue-cured tobacco was better. YATAS102 had higher yield， output value and higher quality economic indicators than Yunyan 87. The overall appearance quality preference and the coordination of chemical components were ideal. [Conclusion] It is suggested that NC-YATAS101 can be used as a back-up variety in a small-area production test demonstration in some tobacco areas in Yongzhou in the year 2020.

由于当前烟草育种的基本程序复杂[1-2]，科研工作者需要付出多年的努力才有可能选育出新的成功品种。烟叶产质量的好坏主要受遗传因素、环境因素共同决定，其中品种因素占25%～35%[3-4]。优良的品种是获得优质烟叶的内在因素[5]，而不同的烤烟品种具有特有的适应区域[6-8]。筛选和推广符合特定区域的优良品种是稳定产量、提高品质最有效的手段和措施[9]。近几年随着国内烤烟烟叶价格的持续上升，工业企业对于质量风格特征突出且价格较低廉的进口烟叶，尤其是美国、津巴布韦和巴西等地的烟叶需求持续上升。……
