Abstract [Objective] The aim was to select the suitable fluecured tobacco varieties for Baihe Area. [Method] The growth period, botanical traits, agronomic traits, the situation of disease incidence in field, economic traits, chemical components and the coordination of comprehensive traits of three fluecured tobacco varieties, K326, Yunyan 87 and Qinyan 96, were comparatively analyzed, and then ten traits of these three fluecured tobacco varieties were evaluated comprehensively by TOPSIS method. [Result] The growth period of Qinyan 96 was the longest, and that of Yunyan 87 was the shortest; Qinyan 96 showed better in agronomic traits, yield and single leaf weight; Yunyan 87 showed better in economic traits; three fluecured tobacco varieties showed stronger resistance to disease. The comprehensive evaluation results showed that Yunyan 87 was the fiest, Qinyan 96 was the second, K326 was the third. [Conclusion] The comprehensive evaluation value of Yunyan 87 is the highest, so it has better adaptability in Baihe Area.

烤煙品种对烟叶生产的贡献率为25%~30%,是决定烟叶产质量和获得理想经济效益的关键因素[1-2]。不同烤烟品种对生态环境的适应性不同,在不同生态条件下品种的农艺性状、产质量及抗逆性等性状都有一定差异[3-5]。只有将品种特性与当地自然条件有效结合起来,才能充分发挥优良品种的生产潜力[6-9]。为此,笔者对3个烤烟品种在该烟区气候条件下的生物学性状和质量差异进行研究,以选择适宜该烟区种植的烤烟品种。

1 材料与方法

1.1 试验材料

选用陕西省烤烟良种区域试验白河试点2011~2013年试验部分数据进行分析。参试品种共3个,分别为K326、云烟87、秦烟96。

1.2 试验方法

1.2.1 试验点基本情况。

试验于2011~2013年选择在陕西省安康市白河县仓上镇天宝村三组进行,海拔870 m,试验地土壤为黄棕壤,地力中等,肥力均匀,排灌方便。……
