摘要 [目的]篩选出适宜广东种植的晒黄烟品种。[方法]对大叶青梗、81-26、小叶青梗3个晒黄烟新品种进行大田试验，调查研究其农艺性状、经济性状、物理性状、化学成分、感官质量等各指标的差异。[结果]3个参试的晒黄烟品种中，81-26农艺性状较好，株高、茎围、最大叶面积优于其他品种;大叶青梗经济性状表现最佳，产量、产值分别为1 612.56 kg/hm2、78 483.30元/hm 显著优于81-26与小叶青梗，并且外观质量表现最好。小叶青梗总糖与还原糖含量最高，81-26总植物碱与全钾含量较高，不同晒黄烟品种化学成分均较为协调。工业评价方面，81-26的含梗率低，工业利用性好;大叶青梗评吸质量最佳，具体表现为浓度适中、香气饱满、杂气少。[结论]3个晒黄烟品种中，大叶青梗最适宜在广东南雄种植。

Abstract [Objective] To screen out yellow sun-cured tobacco varieties suitable for    tobacco planting in Guangdong Province.[Method] Three new sun-cured tobacco varieties， Daye Qinggeng， 81-26， and Xiaoye Qinggeng， were tested in the field to investigate the differences in agronomic， economic， physical properties， chemical constituents， sensory quality and other indicators.[Result] Among the three tested yellow sun-cured tobacco varieties， 81-26 had better agronomic characteristics， and the plant height， stem circumference and maximum leaf area were better than other varieties; the economic characteristics of Daye Qinggeng were best， the yield and output value were 1 612.56 kg/hm  78 483.30 yuan/hm  which were significantly better than 81-26 and Xiaoye Qinggeng， and the appearance quality was the best. The contents of total sugar and reducing sugar of Xiaoye Qinggeng were the highest， and the total alkaloid and total potassium of 81-26 were higher. The chemical constituents of different sun-cured tobacco varieties were relatively coordinated. In terms of industrial evaluation， the stem-containing rate of 81-26 was lower， and the  industrial applicability was better. The inhalation quality of Daye Qinggeng was best， which is characterized by moderate concentration， full aroma， less odor.  [Conclusion] Among the three yellow sun-cured tobacco varieties， Daye Qinggeng was most suitable for planting in Nanxiong， Guangdong Province.

优良的烟草种质资源是烟叶优质、适产的重要内因，对烟叶的化学成分、香气特征具有重要影响[1-2]。晒黄烟对环境适应能力强，但由于其收获器官及其用途特殊性，生态条件的差异对重要性状的遗传特性表达影响较大[3]，特别对关系晒黄烟产质量的株形、叶面积、叶片厚度及其质量风格的化学成分具有较大影响[4-5]，将品种的遗传特性和生态环境结合起来，选择适合当地生态条件的优良晒黄烟品种，才能实现晒黄烟的优质、适产。……
