摘?要：为评价不同烤烟品种的生态适应性和筛选适宜贵州毕节烟区种植的烤烟品种，以云烟87为对照，对贵烟202、湘烟5号、云烟116、CC297和CC27等5个品种的农艺性状、田间自然发病率、经济性状和感官质量进行分析，结合一年两点区域试验分析和综合指数法对各参试品种进行综合性状评价。结果表明，云烟116在两个试验点表现均优于对照，适应环境能力强，属广适性品种;CC27在黔西试验点表现优于对照，但是在七星关试验点表现较差，贵烟202和湘烟5号在黔西试验点表现良好，在七星关试验点表现与对照相当;CC297的均价、上等烟率、一年两点区域试验分析和综合指数评价均差于对照。云烟116的农艺性状、田间自然发病率、经济性状和感官质量等综合表现优于对照，适宜在毕节烟区种植。
