The results showed that YN105 had more leaves per plant and coordi- nate chemical composition, and the yield per unit area was 2 221.05 kg/hm2 with the single output of 33 960.00 yuan/hm^2. Its rate of high and medium class leaves was 80.17%, presenting good performances in testing varieties （lines）. The flowering of YN99 was late but showed coordinate chemical composition, and the yield per unit area was 2 128.50 kg/hm^2 with the single output of 33 454.05 yuan/hm^2. Its rate of high and medium class leaves was 83.17%, which also had good perfor- mances in testing varieties （lines）. It was recommended that YN105 and YN99 be moderate planted in Ankang tobacco growing area, but further experiment is needed to confirm.展开更多
