烤烟新品种(系)西南烟区生态适应性研究

Ecological Suitability of New Flue-cured Tobacco Varieties (lines) in Southwest Tobacco Growing Area

为全国烤烟新品种(系)筛选、鉴定、推广提供科学依据,2017年在贵州省兴义市开展全国烤烟品种生产试验,对4个烤烟品种(系)的农艺性状、经济性状、常规化学成分含量等方面进行分析。结果表明,在兴义烟区相同的生态条件和栽培管理下,烤烟新品种(系)间生育期、农艺性状以及植物学性状存在明显差异;云烟207株高最高,为143.3cm;YATAS8有效叶片数最多,但白粉病发生率最高,其上等烟比例和均价最高。云烟207和YATAS8油分含量以及身份较对照差,化学成分均在适宜的范围内。

To provide scientific basis for the screening,identification and promotion of new flue-cured tobacco varieties,national flue-cured tobacco variety production test was carried out in Xingyi City,Guizhou Province in 2017.The agronomic characters,economic characters and conventional chemical content of four flue-cured tobacco varieties were analyzed.Results showed that under the ecological condition and cultivation management in Xingyi Tobacco Growing Area,there were significant differences in growth period,agronomic characters and botanical characters of different varieties.Plant height of Yunyan 207 was the highest(143.3 cm),YATAS8 showed the greatest effective numbers,but the incidence of powdery mildew was the highest,and its proportion of first class tobacco and average price were both the greatest.Oil contents and status of Yunyan 207 and YATAS8 were poorer than those of control.And the chemical components were all within the proper range.
