湘西烤烟新品种(系)区域试验研究

[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。

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

[Objective] To evaluate the adaptability of the six new varieties (strains) of flue-cured tobacco provided by Hunan tobacco breeding units in Xiangxi area.[Method] Taking K326 and Yunyan 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 value,the proportion of middle and high grade 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 produced and demonstrated in small area of test region.
