湘西烤烟新品种(系)区域试验研究

Regional Test of New Flue-cured Tobacco Varieties(Strains) in Xiangxi

[目的]对湖南烤烟育种单位提供的6个新品种(系)在湘西地区的适应性进行评价。[方法]以K326和云烟87为对照,对20708、SY15230、HY1213、CN-1、E9、CS1545共6个烤烟新品种(系)进行小区对比试验,分析比较各个品种(系)的生育期、农艺性状、病害发生情况、经济性状、化学成分和评吸结果等。[结果]新品种(系)CN-1、SY15230、CS1545和20708在产量、产值、中上等烟比例等方面好于对照K326和云烟87,但是评吸结果略差于K326和云烟87。[结论]综合多方面因素考虑,CS1545可在试验地区小面积生产示范。

[ Objective]To evaluate the adaptability of the six new varieties （strains）of flue-cured tobacco provided by Hunan tobacco breeding u-nits in Xiangxi area. [ Method ] Taking K326 ad Yunya 87 as the control, the regional test of the new^ tobacco varieties （strains） 20708,SY15230,HY1213,CN-1,E9,CS1545 were conducted,meanwhile the growth period,agronomic traits,field diseases ,economic characters,chemical composition analysis and sensory of varieties （strains） were analyzed. [ Result ] The yield,output high gade tobacco, etc. of new varieties （lines） CN-1 ,SY15230,CS1545 and 20708 were better than that of the control K326 and Yunyan 87, but sensory evaluation were slightly worse than K326 and Yunyan 87. [ Conclusion] Integrated many factors,the new varieties CS1545 can be pro-duced and demonstrated in small area of test region.
