自育烤烟新品种(系)产量和质量的对比研究

Comparative Research on Yield and Quality of New Varieties(Lines) of Flue-cured Tobacco

以江西烟区主栽烤烟品种K326为对照,在江西信丰烟区进行了烤烟新品系对比试验,对各品系的主要农艺性状、经济性状及烟叶品质特性进行了分析评价。结果表明:GZ005的单位面积产量极显著高于对照K326的,GZ007、GZ001、GZ006的产量均显著高于K326的;GZ007、GZ001、GZ005的单位面积产值高于K326的,但差异不显著;这4个新品系烟叶的内在化学成分协调,株高、茎围、腰叶长宽、腰叶干重的均值均优于K326的。

Using flue-cured tobacco variety K326 as a control,investigated the new flue-cured tobacco strains contrast test in Xinfeng county of Jiangxi province,analyzed and evaluated their major agronomic characters,economic characters and the tobacco leaf quality. The results showed that the yields of GZ005,GZ007,GZ001 and GZ006 were significantly or extremely significantly higher than that of the control K326. The hectare output value of GZ001,GZ005,GZ007 were higher than that of K326,but the difference did not reach a significant level. The intrinsic coordination of chemical composition,plant height,stem circumference,waist leaf width,waist leaf dry weight of four new lines were better than those of K326.
