摘要:

【目的】筛选既能彰显津巴布韦烟叶风格特色、又适宜在云南德宏烟区种植的优质特色烤烟品种,为德宏州特色优质烟叶基地单元的品种布局及后备品种筛选提供科学依据。【方法】以云烟87为对照,选取T16、T20、KRK26、T62、T63和T64共6个津巴布韦烤烟品种在云南省德宏州芒市红塔集团遮放基地单元进行品种对比试验,调查各品种生育期、农艺性状、经济性状,评价初烤烟叶外观质量并测定其主要化学成分含量。【结果】各品种在苗期、团棵期差异不明显,从现蕾期开始,津巴布韦烤烟品种较对照云烟87生育期推迟,全生育期达160 d左右;除T20外,6个津巴布韦烤烟品种的田间长势均比对照云烟87强;各参试品种均有普通花叶病发生,但津巴布韦品种的发病率均低于对照云烟87;津巴布韦烤烟品种的产量和产值均高于对照云烟87,其中KRK26的产量和产值最高,分别达3109.50 kg/ha和83580.00元/ha;各品种初烤烟叶外观质量整体表现较好;总糖、还原糖含量较高,烟碱含量较适宜,各部位化学成分较协调。【结论】6个津巴布韦烤烟品种综合表现与当地主栽品种云烟87相当,其中KRK26抗病性较强、产量和产值最高、化学成分较协调,可在云南德宏烟区进一步试验与推广。

【Objective】In order to provide scientific basis for distribution of varieties in tobacco base unit and reserved variety screening, some tobacco varieties suitable for planting in tobacco-growing area of Dehong, Yunnan were screened, which could fully demonstrate style and characteristics of Zimbabwe tobacco. 【Method】The experiment was conducted to compare six tobacco varieties(T16,T20,KRK26,T62,T63,T64) from Zimbabwe in the tobacco base unit of Hongta Tobacco(Group) Co., Ltd. in Dehong, Yunnan, with Yunyan 87 as control. During the cultivation, the growth period, agronomic characters and economic characters of six tobacco varieties were investigated. And the appearance quality of tobacco leaves were evaluated at the beginning of flue-cured tobacco process, and the contents of chemical components in tobacco leaf were determined. 【Result】The results showed that, there were some nonsignificant differences in seedling and rosette dates among all varieties. After flower budding stage, the growth period of tobacco varieties from Zimbabwe were longer than that of Yunyan 87, and its whole growth period were up to 160 d. The varieties from Zimbabwe grew better than that of control, except for variety T20. Moreover, all tesed varieties had been infected with TMV, thus common mosaic disease occurred in tobacco plants. However, the tobacco varieties from Zimbabwe showed lower incidence of mosaic disease than Yunyan 87. The yield and output value of varieties from Zimbabwe were higher than those of Yunyan 87, of which, the yield and output value of KRK26 were the highest, and up to 3109.50 kg/ha and 83580.00 yuan/ha, respectively. The leaf appearance qualities of all tobacco varieties were better generally at the beginning of flue-cured tobacco process. Besides, the contents of total sugar and reducing sugar were higher, the nicotine was appropriate, and the chemical components in different parts were more coordinated. 【Conclusion】According to comprehensive performance, all tobacco varieties from Zimbabwe is comparable to main local cultivar Yunyan 87, especially KRK26 with  strong disease resistance, the highest yield and output value and coordination of chemical components. Therefore, these tobacco varieties from Zimbabwe should be further tested and popularized in Dehong tobacco area.
