The quality of flue-cured tobacco is closely related to the quality of cigarette products and farmers＇ economic benefit in planting tobacco, as variety is the foundation of flue-cured tobacco production, so it isimportant to explore the ways of improving the quality of flue-cured tobacco in China in view of varieties. Inthis paper, the evaluation criteria for the quality of flue- cured tobacco and the influencing factors weresummed up on the basis of literatures of domestic scholars, and the effects of varieties on the quality of flue-cured tobacco were analyzed combined with the actual situation of tobacco production and breedingexperience. It was supposed that the evaluation on the flue-cured tobacco quality should be combined with thespecific demands of cigarette industries for the quality of tobacco leaves, and concerning a particular ecologicalenvironment, the variety was the most important factor among many factors which affected the quality of flue-cured tobacco. The effect of varieties on the quality of flue-cured tobacco included the genetic background ofvarieties which determined the quality of tobacco leaves, the interaction of varieties and ecological conditionswhich strengthened the quality of tobacco leaves, the anti-adversity and resistance of varieties which ensuredthe quality of tobacco leaves, and the harmony of varieties with production technologies which enhanced thequality of tobacco leaves. Accordingly, the paper put forward the ways to improve the quality of flue-curedtobacco in China in view of varieties, including：（1） to carry out the breeding aiming at the practicalrequirement of flue- cured tobacco production;（2） to make a rational distribution of flue- cured tobaccovarieties and select the optimum variety for the suitable area;（3） to develop suitable planting technique for good varieties according to their characteristics.
