The leaf number of KY907 was lower than CK, and other varieties were higher than CK. Growth period of six varieties has different from 1 d -3 d, which were middle-late maturing variety. ②The resistance data indicated that the tobaccco angular leaf spot and tobacco hollow stalk were found on all varieties, the virus disease incidence of CK was highest, that of KY8959 was lowest among all tested material. Black shank disease of varieties were not found except KY907. ③The economic character analysis indicated that the yield of TN90,, KY8959, KY907 were higher than CK, and KY907 was the highest, and next was TN90 . The output value of KY8959 was the highest, and next was KY907, and the first-class tobacco propor- tion of TN90 was the highest. ④TN90 and KY8959 had better total characteristics so they were consider primarily to be ggood quality Burley tobacco varieties, which appropriated for planting at Binchuan.
