云南烟区12个烤烟品种适应性研究

A Study on Adaptability of 12 Co-bred Flue-cured Tobacco Varieties in Yunnan

为了解云南省烟草农业科学研究院与美国北卡罗来州立大学合作选育烤烟品种在云南烟区的主要特性，在云南海拔1600～2100 m植烟区域内进行了12个合作选育品种比较试验。结果表明，12个合作选育品种主要植物学性状和农艺性状（ NC-YATAS7除外）与对照K326差异不明显。 NC-YATAS8、NC-YATAS6、NC-YA-TAS9产量和产值效应高，丰产性和适应性好，NC-YATAS5、NC-YATAS10丰产性和适应性次之，NC-YATAS2丰产性好，适应性较差，其他品种较差。各品种原烟成熟度好，叶片结构疏松，NC-YATAS1、NC-YATAS6、NC-YATAS8原烟感官质量与K326相当，NC-YATAS7、NC-YATAS2、NC-YATAS11接近K326，其他品种比K326差。 NC-YATAS8和NC-YATAS6农业性状和原烟感官质量表现较好，具有较好的推广应用前景。

In order to understand the characteristics of flue-cured tobacco varieties co-bred by Yunnan Academy of Tobacco Agricultural Sciences and North Carolina State University,U.S.A,a comparative experi-ment on 12 co-bred varieties was carried out in the regions at the altitude from 1 600 m to 2 100 m in Yunnan with K326 as the control.The results showed that there were no remarkable differences in the botanical and ag-ronomic characteristics（ except NC-YATAS7） between the 12 varieties and K326.The effects of yield and out-put yield of NC-YATAS8,NC-YATAS6,and NC-YATAS9 were higher than those of the other varieties,and their high-yielding capacity and adaptability were the best followed by NC-YATAS5 and NC-YATAS10,the high-yielding capacity of NC-YATAS2 was the best,but its adaptability was poor.And the other varieties were poorer.All the varieties showed good maturity level and leaf structure after flue-cured,the sensory taste quality of NC-YATAS1,NC-YATAS6,and NC-YATAS8 was equivalent to that of the control K326,and that of NC-YATAS7,NC-YATAS2,and NC-YATAS11 was close to that of K326,that of others were poorer than that of K326.NC-YATAS8 and NC-YATAS6 showed better comprehensive performance of agricultural characters and the sensory taste quality,showing broad application prospect in the production of tobacco leaves.
