Abstract: For maintaining its fresh aroma style,flue-curing of cv.CB-1 was experimented with middle leaves,the effects of yellowing and wilting degrees on the aroma style of cured leaf were studied by aroma style index method.The results showed that the cured leaf maintained its fresh aroma style independent of yellowing degree;however,if wilting was at a too low degree,the cured leaf would be "fresh inclining to medium" or "medium inclining to fresh" in aroma style.For the purpose of maintaining the fresh aroma style of cured leaf of cv.CB-1,the dehydration of tobacco leaf at yellowing stage in flue-curing must be carefully attended and the rational management of dehydration should be stressed
