Research on the Adaptability of New Flue-cured Tobacco Varieties(Lines) in Ankang Tobacco Growing Area

为筛选具有安康山地烟区特色的烤烟新品种（系）,在安康主产区设立2个试验点,以烤烟品种K326、‘云烟87’和‘秦烟96’为对照，对新引进的6个烤烟新品种（系）的适应性进行比较筛选试验。结果表明，YN105单株叶片数多，化学成分协调，单位面积产量为2221．05kg／hm^2，单产值为33960m元／hm^2。上中等烟率为80．17％，在参试品种（系）中表现好；YN99中心花开较迟，化学成分协调，单位面积产量为212850kg/hm^2，单产值为33454．05元／hm^2，上中等烟率为83．17％。在参试品种（系）中表现较好。建议YN105和YN99新品种（系）可作为搭配品种在安康主烟区适度种植，但还有待进一步试验验证。

Research on the Adaptability of New Flue-cured Tobacco Varieties （Lines） in Ankang Tobacco Growing Area

In order to screen new flue-cured tobacco varieties （lines） with mountain characteristics of Ankang tobacco growing area, the adaptable selection experiments of 6 newly introduced flue-cured tobacco varieties （lines） were carried out at the 2 set test sites in Ankang producing areas with K326, ＇Yunyan 87＇ and ＇Qinyan 96＇ as controls. 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.
