To investigate the matching degree of different flue-cured tobacco cultivars (under the similar ecological condition) leaf quality with tobacco blend grouping of Chinese type cigarette, the comparative study of the main cultivars in China (i.e. Yunyan 85,Yunyan 87 and K326) were carried out in relation to growth, yield, curing and quality characteristics of tobacco leaves based on local standardized production techniques. The results showed that, among the tested three cultivars, the growing period of Yunyan 85 was the shortest, growth vigor of Yunyan 87 and K326 was similar in field, and the yield of Yunyan 87 was the highest. Additionally,chemical compositions of all tested cultivars were basically harmomous, except the relatively high content of nicotine in upper leaf of Yunyan 85 and Yunyan 87. Smoking evaluation results indicated that these three tobacco cultivars had better aroma and less offensive odor, and sweetness of Yunyan 85 was slightly better.%为探讨相近生态条件下,不同烤烟品种烟叶品质适合卷烟叶组配方的程度,对目前我国主要种植的云烟85、云烟87和K326烤烟品种进行了田间生长、烟叶产量、烘烤和品质的特性对比研究.结果表明,云烟85的大田生育期最短,云烟87与K326田间长势接近;云烟87产量最高;除云烟85和云烟87上部烟叶烟碱含量偏高外,其余化学成分基本协调;评吸结果表明,3个品种烟气香气质均较好,杂气较轻,云烟85在甜度上略好.
