[ Objective] The purpose was to analyze the main agronomic traits of self-nurture new tobacco lines of Hubei Province, and study their dehydrating properties. [Method] Flue-curing characteristics of three flue-cured tobacco lines, A7, A9 and HB074, were analyzed by comparing to Yunyan 87. [ Result] The leaf width of three new flue-cured tobacco lines were all thinner than that of contrast variety Yunyan 87, while the water lose speed were faster or equivalent than contrast variety Yunyan87, so it should he noticed to moisturize, turn yellow, and fix color in time during flue-curing. [ Conclusion ] The study provides a baking technical basis for popularization of A7, A9 and HB023.%[目的]分析湖北省自育烤烟新品系主要农艺性状,并研究其烘烤时的失水特性.[方法]以云烟87品种为对照,分析了3个烤烟品种(系)A7、A9和HB074的烘烤特性.[结果]3个新品系的叶片厚度均比对照云烟87薄,失水速度快于云烟87或与云烟87相当,在烘烤中要注意保湿变黄,及时定色.[结论]该研究可为A7、A9和HB023的推广提供烘烤技术依据.
