贵州省不同生态地区烤烟品种

[目的]为贵州省烤烟品种换代、品种布局提供依据。[方法]以K326和云烟85作为对照,研究了贵烟4号、贵烟11号、黔西1号、韭菜坪2号和GS045共5个烤烟品种的生育特性。[结果]韭菜坪2号和贵烟4号的主脉较粗,K326、云烟85较细。韭菜坪2号、贵烟4号叶肉组织较厚,GS045较薄。贵烟4号、贵烟11号长势较强,K326较弱。打顶期株高较高的品种是贵烟11号(99 cm),较低的是K326(81cm);叶片较多的是贵烟11号(19.2片),较少的是韭菜坪2号(17.3片);腰叶较大的是云烟85和GS045,最小的是K326;产量最高的为GS045,K326最低;云烟85外观质量最好,贵烟4号最差。[结论]5个供试品种产量和对照差异不大。黔西1号和韭菜坪2号综合表现最好,贵烟11号表现最差。

Preliminary Study on Selection on the Flue-cured Tobacco Varieties in Different Ecological area in Grizhou

[Objective] The study aimed to give a base for the variety replacement and variety distribution of flue-cured tobacco in Guizhou.[Method] With K326 and Yunyan 85 as CK,the growth characters of five varieties of Guiyan 4,Guiyan 11,Qianxi 1,Jiucaiping 2 and GS045 were investigated.[Result] The midribs of Guiyan 4 and Jiucaiping 2 were thick and that of K326 and Yunyan85 were thin.The mesophyll tissues of Jiucaiping 2 and Guiyan 4 were thick and that of GS045 was thin.Guiyan 4 had Guiyan 11 had a strong growth energy and K326 had a weak one.In topping stage,the plant height of Guiyan 11 was higher(99 cm)and that of K326 was lower(81 cm);Guiyan 11 had more leaf number and Jiucaiping 2 had less one;Yunyan85 and GS045 had big waist leaves and K326 had less one;the yield of GS0 45 was highest and that of K326 was lowest;the appearance quality of Yunyan 85 was best and that of Guiyan 4 was worst.[Conclusion] The yield of 5 varieties had a little difference from that of CK.Qianxi 1 and Jiucaiping 2 were best in comprehensive performance and Guiyan 11 was worst.
