Abstract
Cytoplasmically male-sterile flue-cured tobacco cultivars, which were derived by backcrossing normal male-fertile cultivars to a male-sterile one containing Nicotiana megalosiphon cytoplasm, were compared to cultivars which were used as a recurrent parent. The male-fertiles produced significantly higher yield, return index, and percentage of reducing sugars than the male-steriles. The latter gave slightly improved grade index, and maturity index, higher total alkaloid content, and lower lamina weight than the fertiles but these differences were not significant.
