全国烤烟品种区域试验咸丰点试验分析

目的]为品种审定、推广、合理布局利用提供科学依据。方法]2015年,在咸丰开展了以K326、云烟87为对照品种的全国烤烟品种区域试验。结果]农艺性状表现较好的新品系是CF228、YN119、HB030、贵烟8号,其次是云烟207、贵烟13号、贵烟5号、09011;经济性状较好的是CF228、YN119、HB030,其次是云烟207、贵烟5号、09011、贵烟13号;质量性状较好的品系是云烟207、HB030、贵烟8号、CF228,其次是YN119、贵烟5号、贵烟13号、09011;综合经济性状和质量表现较好的是CF228、HB030、贵烟8号。经过化验和评吸结果:贵烟8号、贵烟5号、贵烟13号、YN119总糖含量偏低,YN119的氧化钾含量偏低,其余参试材料内在化学成分较适宜协调。09011、贵烟8号与对照K326和云烟87的外观品质因素相当,其他品系的烟叶外观质量均比对照品种K326和云烟87外观质量差。评吸质量除贵烟8号、贵烟5号较差以外,其他参试品种(系)均与对照品种相当。结论]HB030、CF228、贵烟8号综合性状较优。

Analysis on Regional Test of National Flue-cured Tobacco Varieties in Xianfeng Point

Objective]To provide a scientific basis for variety certification, extension and rational layout.Method]The national tobacco vari-ety regional test was conducted in Xianfeng point in 2015 using K326, Yunyan 87. Result] The varieties with better agronomic traits were CF228, YN119, HB030 and Guiyan 8, followed by Yunyan 207, Guiyan 13, Guiyan 5, 09011.The varieties with better economic characters were CF228, YN119, HB030, followed by Yunyan 207, Guiyan 5, 09011, Guiyan 13.The varieties with better quality traits were HB030, Yunyan 207, Guiyan 8, CF228, followed by YN119, Guiyan 5, Guiyan 13, 09011.The varieties with better comprehensive economic charac-ters and quality were CF228, HB030 and Guiyan 8.The total sugar contents of Guiyan 8, Guiyan 5, Guiyan 13, YN119 were low, the potas-sium content of YN119 was low,the intrinsic chemical composition of the other tested varieties was compatible.Appearance quality of 09011, Guiyan 8 was equivalent to K326 and Yunyan 87, appearance quality of the other strains was poorer than K326 and Yunyan 87.In addition to Guiyan 8 and Guiyan 5,the overall performance of the other tested varieties were equivalent to the control species.Conclusion]HB030, CF228, Guiyan 8 have better comprehensive traits.
